Maybe the Iranians can have a auto inhaler on their space helmets.
Also soldiers should have to refill their camelbacks at the start of every mission and have to drink several gallons a day from it or else they pass out and stuff like how that cool DayZ game does it, because again realism = fun.
And since so many seem to be on this crusade to make Arma super realistic and take the fun out of it, let's add a feature where soldiers have to eat, poo/pee, sleep, add baby wipes for combat showers and let's not stop there, let's add moar realism by requiring PFT's and if your digital soldier fails you can't play until you pass the next PFT.
Ohhh yeah and a ingame trading system that allows you to trade MRE's with eachother mmmmm Jambalaya my favorite!
Also let's include an enlistment form relevant to the player's nation of residence to serve in the armed forces so they can experience how cool and fun war is...Yeah let's keep adding realism and not make a good game. /rant
