3 Commando Brigade

5.56mm vs 5.45mm vs Osprey vs 6b23.

New 3CB BAF weapon pack is next on the list for releases :). Mod team is hard at work testing and finalizing. All ballistics have been painstakingly replicated by Lifetap and Andy to be as accurate as possible - so that should be something to look forward to . 

So in conclusion, shoot them in the face.

Cant say I really felt like having problems with the L85. On the public server I usually stick to british guns and equipment. What feels a bit weird is the feedback when you git somebody. It looks a bit annoying if you hit somebody in the chest one time and he just shrugs it off. After that you hit him another time and he stills just acts like you poked him and only the third shot drops him.

Yeah, that's a major issue with the ArmA series (and most FPS, really). Shooting somebody might cause some blood to appear, but it'll usually only decrease some magic "hitpoints" value and only once that reaches zero (or some other constant) the guy drops dead/unconcious.

Ideally, I would like enemies to 'ragdoll' to the ground if they take a 'significant' hit, wait a short time and then start to get up again. 
But, iirc, the ragdoll system in arma is very very limited and you can't really "script" a unit to ragdoll. You instead have to spawn heavy, invisible things, slam them into a unit at high speeds (meaning you need to make them invulnerable for a short period since they'd otherwise get killed by the impact), then delete the heavy object you used, re-enable damage taking, re-sync unit positions...etc. 
It's ugly and means that ragdolling "live" units is very very hard.

ACE3 will "just" improve the ragdolls a bit, but as you can see not on impact and only on death.

Ragdoll was something I talked about in my ACE 3 First Impressions post (scroll down for videos).
Does look like a nice improvement - video MeFirst posted shows it well.
