Title: A question for our ground military guys

What would be the likely cause for this?  What would you have needed to do to prevent, and in the chance that it happens despite procedure, what do you do in this case?  I get the feeling there are steps that have been missed. :headscratch:

As a retired 11C (Mortarman), I would say that it was due to a cook-off of the charges,
 due to an overheated Mortar tube. And improper dropping(Indexing) of round by Assistant Gunner.(Main reason)
Charges should never come in contact with Mortar Tube. Proper indexing( inserting round in tube) of round would have prevented this
And possibly contributing- Dirty tube
Not sure how many rounds were fired before this happened, but was a common worry.
The way to correct this would be as follows(depending upon Mission and War/Peace).

1) Let Mortar tube cool on own.
2) Pour water or other liquid to cool tube down.
3) Urinate (yes Urinate) on tube to cool down.
4) If available - change tube.( Finish Mission with different Gun Track).
5) Retrain Assistant Gunner on proper indexing of round.
6) Swab Tube often                                                                                                                                                :cheers: Oz

Given that at least 2 other rounds had started to hang up in the tube before the last one on film I'd say fouled tube is a pretty good factor there. Another could be a bad batch of ammo with out of spec driving bands. Im unsure about that one though as I have too little experience with the 4.2 mortar anyhow.

This is a mortarman question, not a ground question.

Only thing Infantry and others are supposed to know is if that asset is available and how do we call it in so we can hit all of the combined arms spectrum against our enemy.

You forgot steps 7, 8 and 9.

7. Smack the crap out of retarded mortarman, and give him an Article 15
8. Change your shorts
9. Transfer to 19K, M1A1 tanker

boo

That's a 120mm Mortar, not the 4.2  :aok
Never saw a "bad batch" of ammo. We always fired Nam era ammo in the 80's-90's

11C here as well.

If you've been firing several rounds in quick succession the gases build in the tube and can continue to burn…I've seen 3-5 seconds of flame on an 81.  It might have been gas burning in the tube, then he got his sleeve or glove caught which hung the round long enough to ignite the propellant charges.  If dropped quickly the gun operates normally.

As for the round he threw on the ground, what danger was there from it?  Was it "live" as a result of what happened?

No danger at all, round didn't arm yet. Those are just the donut charges burning, we used to start our campfires with them.

"Little experience" Mav? I thought you were an MP, that's 0 experience isn't it?  :)

Perhaps you should stop trying to "think" and just look at the avatar there...... :P

Old school Armor. Spent almost of my time in the M60's. I did train in the early M1 but really still a 60 guy. (A1 &A3) We had the 4.2 as part of Combat Support Company. When I was XO there I got to hang a few rounds and spent some time as range SO. The Bn CO was of the mind that everyone in the command track should have experience in all the assets available to the Bn, not just the tanks. I tend to agree with him.

Reading the wiki, it's pretty much a bomb?  The fuze on the one he toss didn't do anything, but had it launched, would have activated due to the air?


Also, couldn't you use C4 as a fire source?  Just don't stomp it out? :headscratch:

Ha! Sorry Mav, I just slapped myself for you, didn't mean to insult you by calling you an MP. Tanker is definitely a step up from MP, I can remember a few times that I wished I had a tank. (Javelins were nice though).

 Mortar round has to rotate numerous times before it's armed inflight.
Inside the HE Mortar round is Composition B, not C-4.
High Angle Hell!

C4 is an excellent, slow burning material. (Almost like Paydoh). Made canteen cups of coffee with just a little :)
Heats your meal in a timely manner as well :D

When I arrived at my first duty station and first tour of Germany, it was a CSC, right before integration into HHC. 1984 IRRC.
M-60's were the Main Battle Tank. And this was a Forward Brigade in West Germany.
Our mission area was in defense of Fulda Gap. Mission - Hold off Warsaw Pact till replaced, not relieved.
Full alerts with combat uploads every month. Roll to defensive positions and set up.
We never knew if it was alerts or real world, till after we got to positions.
We'd have been overrun 1st day. 1st BDE, HHC 2Bn 32nd Ar. Kirsche-Goens (The Rock),
the then Federal Republic of Geramny.

The only mortar experience I had was humping to the mortar platoon position under fire to drop the 2 rounds us grunts had to carry for them, then get back to the squaddies. We were the 11 Charlies mules  :rofl
