Churchill AVRE - 290mm?

I don't have any information on this unit. I am assuming that the 290mm is a Howitzer type weapon. Is this correct? I started a QB last night and was given 3 AVREs, but not sure how to use them. :confused:<HR></BLOCKQUOTE>

290mm hollow charge spigot mortar. Worked on the same principle as the PIAT, and was invented by the same guy. Only real use IRL was against fortifications. Although I have read of one case where it hit a tree three yards from a Panther, disabling it through the blast. Very short range (effective about 80 yards, IRL)

The Churchill AVRE is a AFV designed to destroy bunkers, pillboxes, and buildings.

It fires a 290mm Shaped Charge (whoops, that's right, a Hollow Charge Mortar) with the ROF of about 2.25 rounds per minute. The visible projectile in-game is a tan squarish projectile that usually flies at an extreme arc. It has a decent blast radius, but from what I have heard, that there is another weapon that is actually smaller is more effective. I can't recall which, but there was a thread about this a while back. The thread, IIRC talked about that the AVRE really wasn't modelled correctly in-game. Meaning that it isn't as effective as it should be.

But as for general use. Use it to destroy buildings and pillboxes. It is NOT an Anti-Tank vehicle. However it would be useful against field guns.

Recent threads on this subject concluded that the Petard mortar on the Churchill AVRE is incorrectly modelled as Hollow Charge instead of High Explosive. This makes it very effective against pillboxes and armoured vehicles, and useless against buildings or infantry.

Here is one recent thread with a bunch of informative links inside--AVRE thread--but this is quite a docile one. In the past there have been some lengthy threads about the performance of the AVRE, and I'll post the links if I can get the search to work.

Edit: Grrrrr. David beat me to it. Grrrr. smile.gif

You can of course try. If you hit it, you kill it. That hollow charge is probably the most powerful AT shot in the game. And about the least accurate...

Hmm, I am not so sure that this is such a big problem. The AVRE was designed to take out pillboxes and fortified houses on the beaches. It takes out pillboxes beautifully, and the blast knocks out guns too, quite easily. I agree that it is crap against buildings (small light - three hits, small heavy - four hits, large light 5 hits, large heavy nine hits required), compared to a 37mm AA gun. All things considered it is not too bad. The round was based on the same principle, and invented by the same guy, who invented the PIAT. Much of its devastating effect came from the application of the hollow-charge effect (or something like this), not from the amount of explosives. Apparently the bunkers for the coastal guns at Cap Gris Nez proved impervious, but all other bunkers just went.

I think the clinching issue, as discussed in the above threads, was that the Petard round was seen to tumble in flight, thus negating the directional charge characteristic of the PIAT. Indeed I argued that the Petard was a bunker-buster, but others had reason to believe that the Churchill mouting a Petard was more of an all-purpose engineering vehicle designed for destroying obstacles, rather than taking on bunkers in a combat situation. For one thing, the loader is extremely vulnerable to enemy fire.

The AVRE was both. The Petard was desed to deal with bunkers. The crew had an extra guy (demolition NCO), and the vehicle carried so-called Wade charges for destroying obstacles and bunkers. The Petard was used in combat situations, and although I have not finished the book yet, it does not seem that the loader was that exposed from the quotes by the vets who manned the vehicle. Looking at the Churchill design, it is clear that the loader would only be exposed towards the front, the two high tracks giving cover to left and right. He would slide out, and insert the charge into the hole. The charge would probably have tumbled, but according to what I read, as long as it did not turn over completely during flight, it should still have the shaped charge aspect, since it was a large steel-plate on the back of the explosive load that created the effect.

They were certainly used in close combat in many a Normandy village, running around and 'Petarding' (that is a word) the houses.

By all accounts the petard was very effective against houses (and was also used to blast holes in bocage) which is not the case in CM because of the way the blast is modelled.

I have read that strictly speaking the petard round was not hollow charge; that it was in fact similar to HESH. This would explain why the in flight tumble was not so critical and also it's reported blast performance being substantially greater than that modelled in CM.

The exposure to the loader was not very great. Basically the weapon broke downwards for loading which was done through the co-drivers hatch. Only the loaders arm would be exposed.

The guy who is the full bottle on the AVRE is ossie osbourn over at the AFV news forum. He posted a lot of his information over there recently and I note that Andreas has been picking his brains too. smile.gif

Just out of curiosity, who picked your forces? Your opponent? The computer? Tigers versus AVREs? You've been ripped off, man.

It's not Tigers vs. AVREs. It's AVREs

versus German infantry, but the AVREs

will have to do an awesome job of staying

out of LOF of the Tigers. If the terrain

allows it, it could be playable, especially

if the Brits have some other form of AT

capability.

I know a guy (good on you 6+1) who fired an AVRE' (yes, all 290mm/40lb of it) at a sniper. If anyone knows a better case of overkill, I'd like to hear about it. And just for the record the AVRE went under the nickname of "The Flying Dustbin".

AVRE - Armoured Vehicle Royal Engineers

Petard - spigot mortar on AVRE

'Flying dustbin' - projectile for spigot mortar

Funnies - all the weird tank contraptions

Hobart's Zoo - 79th AD

At least that is the terminology that I heard of.

AVRE's were the base tank, on which various technical gimmicks could be installed, e.g. scissor bridges, Bobbins rollers for getting across soft bits of the beach etc.

If infantry is the goal, then CM-wise (not necessarily real-life wise) you would have been better off with the 75mm and 95mm-armed versions.

AVREs suck like explosive decompression blows.

Babra: The computer picked both sides. This is an OnePlayer QB. I started it Monday night got to about turn 3/30. Finished it last night (Tues) after reading the suggestions.

AAR: I WON! Marginal Allied Victory. After reading the forum yesterday, I attempted a few shots at the enemy infantry, but the 290mm's range is so short, that I couldn't get any shots. So used my Infantry (company) to advance to Victory Flag position.

I also mananged to succussfully ambush the Tiger with my 3 AVRE's!!! (yes, amazing, the map was all large wooded hills, with roads. AFV had to say on roads in most cases, let it spot one AVRE as bait.) The Tiger rolled right over the ambush marker. All 3 290mm's fired within seconds of each other! All 3 missed!! All 3 AVRES died burning in the next 30 seconds. But, the Tiger's tracks had been imobilized (3 huge craters around it) and it was away from Victory Posititon, so my infantry was able to hold until turn 30 and win the marginal victory.

God...imagine the concussion effect of that in real life. 3 Flying Dustbins impacting within seconds of each other within a 20 to 30 metre radius. I'm betting that IRL the crew in the Tiger would have been like jelly for at least 48 hrs. after being on the receiving end of that. :eek:
