The best thing with ARMA is realism, not becouse its always the best done realism.. but that its there and you can do it!!
Senarios when you have a Ally with broken leg or badly hurt you should be avalable to put him in a veicle or somthing save until a medic comes or to a heli who flys him away..
I hope people will think the same about me saying, just having small stuff like this makes ARMA what it is, Realism at its best.
Best Regards
