srsly man, go prone... you run throught town with you`r buddies spread out, and you run into a guy, not see him from a distance, but bump in to him, by the time you tell your m8s to go prone or be like"it`s me it`s me dont shoot" he, will light you up, because he`s alone and he knows there are no friendlies in the vacinity, he has no buddies to ask them to go prone and do a frienly check. the reason we use outsideofthegame comms is because the the character customisation, and variety of clothes is so little, that all players look the same, even if u decide to carry only green bags, or only pink hats, its still not doing for us. on the other hand, as the creator of this post suggeted, if we will be able to rip up our white shirts(creating hand made armbands) for example, and tie them around our arms,legs,heads,guns, you name it, and immediately identify our friends, even if we are all dressed in military gear, squad of asian ladies, this would even stear some of us(definitely me) into using direct voice chat,or ingame radios, for better immersion. So no! No more of this stupid prone friendly checks, this is SA for god`s sake, time of going with what worked(effectively) for your team is over, its time for some innovation and efficiency! Lol talking about arm bands, innovation...))
