Naizarak, in my country what is conventional military, women are employed in font line infantry.
I know, because there are 3 women serving in same company im in, and more in different companies in this army base.

They can handle the mental and physical stress, but its about what happens after few years of service, some of women cannot handle it after few years active service in frontline due degradation in muscle tissue and bone joints and back injuries because stress it puts on their bodies, men wont have that problem.

ARMA 3 is based on year 2035, by that year we will have more and more women fighting in front line, so it should simulate year 2035 and should include female models.

@Corona2172, yes they are serving in front line roles, im serving in same damn company as they are, they have better fitness and pressure tolerance than some of the males in here.

At this moment, i know 3 women who are actively serving in front line infantry roles, they are serving in us ranger equivalent role.
Women need pass exactly same physical requirements as men to qualify to work, they go trough exacly same training as men.
Long as they pass same tests and training as men, im fine with them being at frontline fighting for their country.

Yes, Arma 3 should create female models and voices just because in modern day combat you see increasing amounts of females serving in more and more demanding roles.

I agree, recoil is bit too high compared to real world.
I own serveral guns from Semi-Auto SAKO M92 7.62x39 and AR15 5.56x45 assault rifles to Sako TRG-42 .338 Lapua Magnum sniper rifle so i can pretty accurately describe what kind of recoil real guns have.

SAKO M92 with 7.62x39 round, from kneeling position much less recoil than 6.5 round in ARMA3, aim wont lift up much as in ARMA3 and you can re-target much much quicker than in ARMA3.
AR15 5.56x45, even less recoil than Sako M92 7.62x39 round, you can pretty much keap it on target with only small recoil, more accurate at short and medium ranges than 7.62x39 but with less power on impact.
Sako TRG-42 .338 LM, while standing and kneeling heavier recoil than 6.5 round in ARMA3, less recoil on prone, can re-aquire target much quicker than in ARMA3's marksman rilfe with or without bipod but requires manual reload since my gun is bolt action rifle.

My weapons are litle modified for my personal use, different stock and usually SCOT-18 GipPod at front in my 7.62x39 and 5.56x45 guns.
Sako TRG-42 sniper rifle is equipped with bipod.

Edit: And yes like Roddy15th said, human body naturally tries get back to target quick as possible, so in ARMA3 it shouldnt take the aimpoint so far away from target.
