I don’t know how many times I’ve watched the first five minutes of the movie “Top Gun”. Launching an aircraft took a coordinated effort from many sailors. Different colored helmets, vests and the tools they used, including exhaust blast ramps and the catapult trigger, required process precision. The military has got that right!
The Combat Assault is a precision process we used in Vietnam to insert infantry troops into the field to do whatever their mission required. It involved many distinct units within the Division and often different branches of our military and sometimes foreign militaries.
Some Veterans of the Vietnam war are not interested in anything Vietnam then or now. I am not one of those veterans. I grew up on war movies showing courage, determination, sense of purpose and feats of heroism. The first wave of Vietnam related movies including Apocalypse Now, Deer Hunter, and Full Metal Jacket were all political statements and definitely not about courage, etc. or even the greatest evolution in jungle warfare, the helicopter as a direct combat tool, pioneered by the 11th Air Assault (Test) at Ft. Benning, Georgia and perfected in Vietnam. Transportation units were transformed into Assault Helicopter, Assault Support Helicopter, Air Cavalry, Arial Rocket Artillery, and other direct combat units. None of the Vietnam movies represented actual combat aviation units correctly. Even Mel Gibson’s “We Were Soldiers” fell short of that bar although closer than any other effort to that point. However, that movie showed the creed of combat helicopter pilots better than any other in that we worked for the infantry. When called by the infantry, we came. It did not matter about the weather, the time of day or night, or how hot the LZ, we came. They called; we came! I will say this though, Wagner’s “Ride of the Valkyrie” was a nice touch in Coppola’s version of “Heart of Darkness” by Joseph Conrad.
The “Combat Assault” that we flew was I would guess about 30% of our daily life. About 60% of our flight hours were what we called “Logistical Resupply” or LOG for short. The remaining 10% was made up of a wide variety of specialty missions like “Command and Control” (CC) where we flew Battle field Commanders and their bank of radios, Fire Fly which were also known as Night Killer Hunter, Psy War, Special Forces/Long Range Recon Patrols (LRRP), POW transport, and even flying out to Navy Aircraft Carriers. Today’s Blog entry will be about Combat Assaults.
Combat Assaults are multi ship missions. The assault itself is performed by group of aircraft we called “slicks”, armed with two pedestal mounted machine guns and loaded with Infantry Troops. The leader of this group of aircraft has a mission radio call sign of “Yellow One”. The rest of the group’s/formation’s call signs are Yellow Two, Three, Four and so on. If the group consists of more than 6 aircraft, then a second color was used for the 7th through 12th aircraft. Typically, the 7th aircraft was White One, the 8th, White Two and so forth. I’ve been revisiting “Star Wars” movies lately and the Resistance labels their X-wing fighters the same way. I wonder if George Lucas copied us in his productions.
The Combat Assault force I talked about above also included escort “gunships” that we just called “guns”. They were also UH-1 Hueys but earlier models that were specifically configured to carry weapons and ammunition. Around 4 months into my tour, our gun company started trading them in for AH-1G Cobras. These gave the gunships about a 300 horse-power upgrade, about 1/4th the frontal area, and a new rotor system giving them additional speed and ammunition carrying ability. Typically, there were a pair of guns per 6 assault aircraft. They were supplied by a sister Company and in the scenario used below, they will have the call sign “Tomcat”.
So far in this precision “Combat Assault” I have described two separate Army units working together. The troop-carrying Huey “Slicks” led by call sign Yellow One (in our case, B Company, 229th Assault Helicopter Battalion) and a light fire team (2 AH-1G Cobra gunships) call sign Tomcats from D Company, 229th Assault Helicopter Battalion.
Now I’m going to add the Artillery support. There are two types of artillery used in a combat assault if a tube battery is in range of the intended assault. In our scenario, a 105mm howitzer battery will be in range (about 11,000 meters). The second type of artillery is a rocket intensive Huey Cobra that carries 2 each 19 rocket pods and 2 each 7 rocket pods on the pylons instead of Gatling style mini guns like the escort gunships. They are referred to as Aerial Rocket Artillery (ARA) and they have the call sign Blue Max and in our case are from C Company, 2nd Battalion, 20th Artillery Regiment.
At this point I’ve described, counting the infantry unit, elements from five different Army units involved in this operation. Depending on the size of the enemy threat on the ground, there could be two other branches of military involved. The first, and often used, is the Air Force. They provide carpet bombing from B-52’s and more often “Tactical Air” provided by fighter jets of all kinds. The second and rarely used was Naval gunfire. I recall it being used once in my first tour. The Battleship New Jersey was very impressive using their 16” guns on ground targets in Vietnam.
OK, what is the sequence and purpose of each element in this precision Combat Assault? The first, of course, is getting the intelligence from many sources that are used to determine the location and size of an enemy force. Sources of intelligence include interrogation of POWs and other indigenous people, Special Forces operations, enemy activity against helicopters and so on. As a lowly helicopter pilot, we rarely knew the source of the mission. Once the higher-ups decide there is a need to put troops on the ground, the planning begins.
The first action generally involves tube artillery, who prepare the landing zone or soften it up if you will. The purpose is to kill the enemy, destroy fortified positions, and otherwise move enemy troops away from the intended landing area. The relative safety of the infantry and aircrews during the landing and distribution of infantry is the concern. Of course, we can’t land in the middle of an artillery barrage, so the shut-off of the artillery must be known and confirmed before the helicopters enter the prepped area and unload their troops. This confirmation is sent visually. The last projectile of the barrage is a White Phosphorus smoke round affectionately called “The Willy Pete”. The formation of landing aircraft must be on final approach one minute from touchdown when Yellow One confirms and advises his flight over the tactical radio that “I have the Willy Pete”.
So, what keeps the enemy from retaking that landing zone during that one minute of final approach? The answer is Aerial Rocket Artillery (ARA). While the flight leader is lining up our final approach, ARA (two ships normally) joins our gaggle about 1,000 ft above us and behind us, as soon as Yellow One confirms the Willy Pete ARA goes hot. The lead pilot transmits, “Yellow One, Blue Max is going hot”. They place their rocket fire on targets near the landing area that could conceal enemy troops. If they are in fortified positions the rocket barrage serves to keep their heads down so they can’t fire on the helicopters landing. This barrage lasts about 30 seconds. The landing slicks are now at about 30 knots and a couple hundred feet above the ground and very vulnerable to ground fire.
Now the gun escorts go into action. They peel off from the slick formation and go into orbit around the landing zone (LZ) 180 degrees apart and start strafing the perimeter, tree lines, etc., with their mini guns and stay in orbit around the LZ until the last slick unloads and takes off. They may escort the flight back to the troop pickup zone (PZ) or they may stay on station at the LZ depending on the needs of the infantry.
While the guns are doing their thing, our door gunners open up on any target they see and if fired upon, return fire.
The last two things I’ll discuss before I run the scenario below, are aircraft formations and cockpit activities. Aircraft formations are used to simplify control. How many of us have seen a gaggle of geese heading south for the winter or an elementary school teacher lead a line of kindergartners to a school bus? Aircraft formations are always a version of the base “V” formation. Based on the initial mission briefing, and later flight leader observation, a formation is called to get the most grunts on the ground in the least amount of time and is based on the size and shape of the LZ. If we go into a football field size LZ then the basic V formation will get the job done. However, most LZs were either one or two ship size so our typical formations were “sections trail” for two ships or “trail” for one ship. “Sections trail” is a formation with two ship groups in trail with some time spacing between each group. “Trail” formation is where each ship is in single file like that kindergarten line to the bus with time spacing between each ship. The gunship escort is usually two ships (light fire team) or three ships (heavy fire team). The lead gunship positioned itself about 100 meters to the right of Yellow One and back a little. The second gun placed itself to the left of the slick formation and about 300 meters to the rear of Yellow One. When they joined the formation enroute to the objective, they announced to Yellow One, “Yellow One, this is Tomcat 26 with a light fire team. We have you “saddled”.
Cockpit activities become somewhat automatic. There were unit policies and instructions given out by the Aircraft Commander (AC). Rules of engagement and the pilot on the controls were in the bailiwick of the AC. Unit policy included using clear face shields on the helmets (to protect our cool aviator sunglasses if our windshield got shot out), using forced trim on the control stick and having the non-flying pilot keeping a light touch on the controls during the final approach. We generally observed the first and ignored the last two (we twenty somethings were bulletproof after all).
OK, the scenario. If you are still with me at this point, thank you!
Set up:
We are sitting in the pickup zone loading 7 troops per aircraft. We are a group of 6 aircraft. We are Yellow Two positioned left and to the rear of Yellow One, about 15 minutes from the objective and our troops are loaded. You, my readers are the right seat pilot and you currently have the controls. I’m the AC sitting left seat doing final gauge checks and setting radio frequencies. FM 1 on Mission Tactical, FM 2 on company operations, Automatic Direction Finder (ADF) on Armed Forces Radio Station at our home base, and UHF on our home base tower frequency. We are at flight rpm with all engine gages in the green. Our mission briefing has already taken place. After takeoff we will automatically go to “V of three” formation with Yellow Four, Five, and Six going to V of three behind us.
“Flight, this is Yellow One, commo Check.”
“Yellow Two, Lima Charlie.”
“Yellow Three, Loud and Clear”
Yellow Four, Five, Six………….
“Flight, let’s rock and roll.”
I put my hands and feet on the controls and speak through intercom, “I’ve got the aircraft.” You let go of the controls and start your outside clearance scan as I pull in power. I’m fixed on the torque meter as we are fully fueled and have 7 troops as well as our crew of four. In short, we are at Max Gross Weight for our aircraft. As I become light on the skids and proceed to a six- inch hover, I check the position of the stick to see if we are within Center of Gravity limits. As long as I have some aft stick travel to work with so I can bring the nose up to slow down from cruise flight, all is good. I read 40 psi on the torque meter (about 80% available) and nose it over a little to build speed until we reach translational lift, adjust for a 500’ per minute rate of climb and 60 knot airspeed. Yellow One levels off at 1500’ altitude and accelerated to cruising speed of 80 knots. We stayed glued to Yellow One, about 45 degrees to his left and rear and about 3 rotor discs away.
I opened intercom. “You have the aircraft”, and you responded, “I have the aircraft”. I released the controls, set back in my seat and turned up the ADF to listen to Green Tambourine by the Lemon Pipers (Armed Forces Radio played top 40 tunes). This was the quiet before the storm. We had an enroute time of about ten minutes with a few minutes of holding time to set up the final approach to exactly one-minute final. I lit up a cigarette and cooled my jets.
“Yellow One, this is Tomcat 26. We have you saddled”.
“Roger that Tomcat, thanks”. Yellow One continues, “Flight, looks like we have a two ship LZ, go sections trail, 45 second spacing.” Yellow One starts a slow right hand turn as the ships behind us slow down and turn wider to get the spacing. As Yellow Two, we were already in position. From the drifting smoke of the ongoing artillery barrage, Yellow One decided on the approach angle and started his decent to 500’, the starting point of the final minute before touchdown.
“Yellow One, this is Blue Max. We have a light fire team and are on station”.
“Roger that Blue Max, we will be landing to the west.”
“Roger that Yellow One”.
I put my cigarette out and push my floor button to talk on the intercom. “Ok boys lock and load and be alert. We will be the first two aircraft in the LZ. Chief let the grunts know”. I slide my clear visor down and take the controls. “I have the aircraft”.
“You have the aircraft”, you say as you release the controls.
“Flight, Yellow One, I’ve got the Willy Pete”.
“Yellow One, Blue Max is going hot”.
Adrenaline has been building since I took the controls. I lower the power and start the approach staying fairly tight with Yellow One. I’m becoming super aware much like a deer being stalked by a predator. Everything seems to go into slow motion as my senses amp up. I can feel the aircraft talking to me with its subtle motions. It seems relieved as I lower the power and slow down to 60 knots. I can feel small changes in the center of gravity when bodies and weapons move toward the cargo doors with their legs hanging out. This is where Coppola should insert Wagner’s Ride of the Valkyries. I hear the swoosh as Blue Max’s rockets are blazing by. We pass the 30 second mark and we hear our escorts open up on the LZ fringes with their mini guns sounding like the roar of a male lion warning others to stay away from his pride. We are about 200 ft in the air and down to about 20 knots as I scan my landing area deciding the spot and whether I’m touching down or coming to a hover. The closer I am to the ground the less likely there will be grunt injuries exiting the aircraft. My crew chief and gunner are adding to the chaotic fire storm and noise as they lay down suppressive fire on each side of the aircraft. As I pull in more power to stop the aircraft and achieve hovering flight, I feel the aircraft groan like a weightlifter pressing weights overhead. My gunners stop firing as the grunts exit the aircraft and I hold the aircraft reasonably still. The Crew Chief engages the intercom and says “Sir, grunts are clear as the last grunt clears the skids. Yellow One lifts off and I’m right behind him climbing like a bat out of hell, power at 100%. Yellow Three and Four touch down as we clear our spots. The guns stay on station while the grunts set up their perimeter and deal with any hot spots that may come up after Yellow Five and Six clear the LZ.
After we reach flight altitude, I turn the aircraft over to you and unwind with a cigarette as you fly back to the PZ. And we repeat the process in a much less violent way.
This photo is what we see on one minute final of a combat assault. The area circled is the touch down area. The large and very white puff of smoke on the right edge of the circle is from the “Willy Pete” artillery shut off smoke round. The orange red dots and streaks are from the rockets in flight.
That’s all for now. The next installment will be about another category of missions we performed.
