yeah, i sometimes choose to make my own private fire team when it seems that only a few members of my team have a clue what is going on. while I have never really used the fireteam chats and voicechats, it’s still realy useful to know what location they are at and if they are dead or not, etc.
fireteams could be really useful if you’re in an organized team. Rail Gun for example, you could have Alpha team protect the flag. Have Bravo and Charlie focus on the train. Bravo spawns in the Axis cabin, Charlie spawns in the Depot Yard so you get the train from both sides. And then maybe have Delta team to hold the Command Post area and keep that trackswitch raised.
I’m thinking there could be 26 Fireteams, since there are 26 letters in the alphabet. the highest letter I’ve seen is firetea Echo. Foxtrot is F on the phonetic alphabet so that should be next in theory.
