Diffrence between CM and HEI ammo

[McBlemmen]

Hello,

 

What exacly is in combat mix ammo , and what ammo should be used VS tanks?

 

Thank you

[Avilator]

Combat Mix is a mixture of armor piercing and high explosive ammunition in a 4:1 ratio, and is the real-world load for the A-10.

Not the only combat load. We only carry hei currently in Afghanistan.

[Avilator]

Ah, ok. Is that because there aren't really armored vehicles to defeat?

[Snoopy]

Yes sir

[McBlemmen]

So , for soft targets you use HEI , for tanks CM?

Correct

[McBlemmen]

Correct

 

Thanks alot , these forums are so helpfull! :D

 

I dont know if people here care about it , but rep for everyone !

[Habu_69]

Are the round impacts actually modeled to perform differently in the sim?

[Hamblue]

Why do they mix them 4 to 1? to prevent the barrels from overheating with the depleted uranium?

[SmokeyTheLung]

Maybe but I don't think so.

I know the D.U. portion of the round is sub-caliber and encased in a softer metal jacket. Also, the GAU-8 rounds use a plastic (I think) driving band to reduce barrel wear.

I've always figured HEI is loaded to destroy more sensitive and un-armored parts of tanks, like sights and radio equipment. I suppose it also makes an A-10 more effective if it encounters something softer than a well armoured vehicle

CM vs tanks (5 API + 1 HEI).

 

HEI vs turd people (56 grams PBXN-5).

The HEI rounds in CM are simply there for effect on soft targets. If you only have API rounds on board, your effectiveness vs soft targets such as dismounted infantry or even trucks etc. is reduced.

 

And the 4-1 ratios is there because it is the most effective/best balanced mixture. No different to how tracers are normally 4-1 mix with ball rounds etc. Thats all there is to it.

[UCAS]

Also worth noting that when you have CM loaded, the top pipper dot is for API and the bottom is for HEI. Another interesting fact is that a HEI round contain roughly the same amount of explosive as an M2 or F1 hand grenade.

Well.... not the best example- while 4:1 or 5:1 tracer is considered adequate mixing, in the case of tracers, they DO mix them with AP or ball ammo to prevent tracer residue from depositing in the barrel. Also, tracer rounds tend to have worse ballistics (they're much longer for the same weight, and tend to destabilize and tumble easier) and significantly worse terminal performance (at least, in small arms).

 

HEI/AP in CM, though, that's all about mixing the effects for the expected target set. AP kinda sucks against unarmored vehicles and dismounts

Hence why APEX was invented.

An interview with an A-10 Pilot, they said Combat Mix is to 4:1 because they use depleted uranium to punch holes in the tank and the high "explosive" incendiary effects can destroy everything inside of it. In reality if it only had a full load of API, it wouldn't really do an excellent job at killing the guys inside now would it?

[Dragon1-1]

It would, I seriously doubt the HEI would be going through holes made by API, except by luck. Dispersion is too high. It could have some incendiary effect of that sort, but combat vehicles are typically pretty tightly packed, if you can punch a hole, you'll mostly likely hit something important, and spallation will do an adequate job maiming the crew. In fact, it might do it even if you don't quite manage to make a hole, at least in older designs without spall liners.
