Diary 19-25 June 1968

19 June: 1.5 + 1.0 end 5th week [Field strength] 589. 8171 [marginal note the meaning of which is unknown to me] Quiet nite [this is the first occurrence of this notation which appears in almost  every subsequent entry except where the entry is Unquiet nite.] air mobile 2 Co's to W & S of swamp [not otherwise located]. Found documents and 10 RPG 7. Scattered night sightings. C Co. became night Company [do not remember the meaning of this remark]. Repaired Flame Service Unit (FSU) charged 1 FT [flame track] Rec'd ltr & tape ML, ltr Vic. Wrote ML.   

The HHC Flame Platoon was composed of 4 older  model gasoline-driven M113 flame tracks whose cargo compartment was  filled with a complicated, Rube Goldberg-like flame throwing system. The  FSU was a truck-mounted compressor and pumping unit that were used to  refill the flame track's tanks with napalm and compressed gas. A flame  stream was produced by ignition of napalm as it was propelled through a gun-barrel-like device by high-pressure gas. The  stream could shoot about 40 yards. Built for European battlefield use,  the Army sent them to RVN in the belief they would be useful in  incinerating NVA in bunkers. In practice, they were mechanically  unreliable and usually unavailable on the battlefield when needed.  During May-Nov 1968, I never had a combat opportunity to use them. They were tested occasionally during "mad minute" weapon firing at FSB  Rawlins III. They were awesome.   

Butch Sincock was an A Co. Platoon Leader during  the Battle Xom Binh Dong west of Saigon on 26-27 May 1968 (refer to  diary entry for battle details). His 14 June 2004 message reports his  remembrance of a combat use of the Flame Platoon, which I have obviously  forgotten.    

  "They were employed in combat during our  late-May '68 battle just west of Saigon. The two flame tracks were  facing west on the perimeter. Just after dawn on the 27th when the  second wave of attacks began, the concentration of NVA was to our south.  The two flame tracks moved from their positions to a spot on the south  of the perimeter. I don't know who called for them, but presume it was someone at Bn. level.    

  When they pulled up to the perimeter the  soldiers moved away to either side. No one wanted to be next to one  of those things if they took an RPG! The flame drivers came to a stop,  locked the brakes, put the engine in neutral and cranked the engine up  so high that sparks were coming out of the engine exhaust. I think that  was to build up compression in the tanks (2 as I recall).

  I  recall vividly at least one of the flame tracks cut loose with a stream  of flame at a squad (10 +/-) of VC/NVA behind a paddy dike not far  away. When we finally surveyed the battlefield the next day we found  that the flame track had completely neutralized that enemy squad, decapitating one or more of them with the flame stream. It was  pretty gristly. The guys referred to them as "crispy critters." So, I  can testify that they were certainly effective in that combat situation,  although I shared the reluctance of the troops to get anywhere near  them in a firefight."   

This is the way the Flame Platoon Leader, Gary Bennett, remembers the equipment and the combat action described above by Butch:   

  "The Flame tracks had two spheres of  approximately 200 gals. These held 200 gals. of napalm and 200 gals. of  compressed air. As soon as the system was charged, the track was a  rolling bomb and we wanted to discharge that puppy as soon as possible.  The igniters were very iffy and the TC usually carried a cigarette  lighter and a can of lighter fluid to fire off the load coming out of the nozzle.   

  One of the reasons I didn't like to deploy  them was as soon as the flame shot out, everyone stopped shooting to  watch the fire. It was very important to maintain suppressing fire, that  is why there was a machine gunner assigned to the track along with the  coax. The coax was temperamental and often jammed.

  We  did get the word from Battalion to attack. We had two tracks at this event. It was my  understanding that the other two were north in War Zone II with a Cav  unit the flame did stop the attack cold. It actual fused an RPG launcher  to the shoulder of a VC.    

  The flame members carried a Chemical Corps  MOS. I figured this was a war crimes assignment. The tracks were  affectionately known as "Zippos". The support truck was always getting  stuck in the mud. It had a large air compressor and a mixer that used  MOGAS and coconut extract to make the napalm."

From Flame Platoon leader, Bob Renneisen, 1969-70:
  "The  flame stream could be fired on and off through a "gun tube" like affair  that projected over the track driver's right shoulder. The flame was  ignited by a "glow- plug" igniter, which seldom worked. For this reason,  Flame track drivers carried straightened-out coat hangers with a diesel  soaked rag on the end. If the igniter didn't work (usually), the driver would use a  Zippo to light the rag and hold it in front of the tube when they fired  the thing off—kind of like spraying Right-Guard through a match  flame—really high-tech.
 We used the flame tracks weekly at  Rawlins to burn the trash, at which they did quite well. Otherwise we  employed them as part of the perimeter defense at Rawlins with machine guns (M-60) mounted and use of the flame capability  was part of the overall perimeter defense strategy in the event the FSB  got hit."   

From Doug Conn, Recon Plt Sgt, 1969-70: 
  As  far as I can remember they could be lit and relit a small flame on the  front of the tube stayed lit. We took them out to the crescent [nickname  for a part of the TAOR which resembled a crescent as it followed a wide  curve to the east of the Saigon River] in the dry season to burn up  some heavy jungle with huge anthills and bunkers inside. Pictures of this are in my  photo album. If you see a picture of Flame you will notice no other  tracks around. We sure didn't like being close to them. If chuck  [derisive nickname for Charlie, nickname for Viet Cong] got mad he would  aim for them first. I know they were inoperable much of the time. They  were stationed at Rawlins on the right side going in. They did have the mixing truck with them all the time. It was on a deuce and a  half 6X6 truck"
