Where did the issue occur?
RPT log file:
I don't know if it's by ACE design, but technically speaking 5.56 rounds do more damage in RL than 7.62, and it's the main reason 'the world' moved to 5.56 weapons over the 7.62 weapons of post WWII to 70s.
5.56 rounds deform when they hit the human body, and then tumble as they go through the body causing massive damage, and usually don't exit the body.
7.62 rounds enter through a small hole, usually go straight through, and come whizzing out the other side through a small hole (unless it's your skull of course). Small holes, less damage.
Why use 7.62? They fly significantly truer and further, so for accurised fire for DMR and/or sniper rifles it's much better to use 7.62 weapons. Hit people further away, some times twice as far away.
Right round for the right job ;)
I figured it's probably a bug, since in ACE2 7.62x51 dealt a lot more damage than 5.56, in vanilla ARMA 2/3 it deals more damage too. You do seem to make some valid points though (I say seem, because I don't know much about wounding, and have any real experience only with 7.62x39 and 7.62x54).
But what you said above, wouldn't that be the case if the bullet was hitting unarmored targets?
7.62 rounds also don't fragment, where as 5.56 do, this is another of the things which creates permanent cavitation (the big hole it makes as it goes through the body), hence greater wounding potential.
I'd suggest the A2 damage model by BI wasn't the best TBH.
I don't profess to understand how standard rounds of either type perform on soft tissue once passing through armour. I'd say at a top level, that would depend what type of 5.56 or 7.62 round you're using (as there are plenty, some more armour piercing than others), and of course the quality and type of the armour you're punching through. Or not. I'd say given those variables, trying to model that would hard to impossible.
Round vs the human body is the only thing you can really use as a control/level state.
Hm, I think you misunderstood me. I didn't mean how much damage they cause after both of them pass through the armor, if they do pass they will both do enough damage as it is (even if the 5.56 is indeed more dangerous).
What I meant is, 7.62x51 should actually penetrate the bulletproof vest with less bullets than 5.56 (I'll explain at the bottom why I think this is important). Let me just give you an example.
Let's say you have the same type / quality ammo (5.56x45 and 7.62x51).
Now as promised in the beggining, to explain why I'm bringing this up.
So, either they are taking the bulletproof vest into account by some degree, or this is a bug.
I wonder if this was also the case before v 1.54. Unfortunately our community rarely ever uses vanilla assets so I can't confirm whether or not 5.56mm always was more deadly with ACE3 on or not.
But this could very well be connected to the vanilla vest update and not yet fully compensated for by ACE3.
The main reason most military moved to 5.56 is that the average soldier can carry more ammunition and the the recoil of 5.56 is easier to handle. That the bullets break was not intended initially, they where surprised that they did.
5.56 was made to wound soldiers, 7.62 was made to kill.
Besides, if the bullet breaks and doesn't makes it through the body armor it will not do any lethal damage. Perhaps not even damage anything at all. Yes the 7.62 can also be stoped by body armor, but it has a greater penetration and will therefore more likely penetrate the armor.
7.62x51 has greater penetration & effectiveness at greater ranges at the cost of weight and recoil.
The 7.62x51 and the 5.56x45 are both lethal against soft targets.
It's quite different with armored targets.
The 5.56 is known for lacking stoping power against soldiers and vehicles where the greater penetration and energy of the 7.62 is more usefull.
If the bullet fragments or not has nothing to do with the caliber, but with what kind of bullet you use.

Well from what I see, you're pretty much confirming what I said. It definitely should not be harder to kill someone with 7.62x51 than 5.56, quite the contrary.
I had a real short chat with commy2 a while ago, he said if 7.62 deals more damage in vanilla, then it's probably not intended to deal less in ACE3.
Also, please consider fixing this before 3.6.0 (3.5.1 maybe)? I'm generally patient, but this one has a huge impact on gameplay:
Whenever I get any kind of marksman role (mk14 ebr or rahim) I just take the scope, and dump the marksman rifle for a regular rifle first chance I get. Because why would you use 7.62x51mm (less damage, more recoil, smaller magazine). Straight up downgrade compared to 5.56mm.
Or for example, why would you take M240 (7.62x51mm - 100 rounds) if you have a chance to grab M249 (5.56mm - 200 rounds). As it is, M249 kills faster, has less recoil, and to top it off, you get twice as much ammo to shoot without reload.
