You say rude. I say teamwork.
It all depends on you're perspective. I'm not so full of myself to think it's "kill stealing". If you can kill the guy faster than me, go for it! There's plenty of reds to go around for everybody.
It's going to happen so why not just accept it as a positive thing?
Blooz, it is rude behavior. Skyrock is right on!!!
IF you read my post above you will see why.
If your hord of friendlies (aka your squad) are playing "chicken wing" (that's a vet term...you prob don't know what it is) then that's fine....just don't do that to someone you don't know.
Since you brought up "teamwork"
Teamwork - the actions of individuals, brought together for a common purpose or goal, which subordinate the needs of the individual to the needs of the group. In essence, each person on the team puts aside his or her individual needs to work towards the larger group objective. The interactions among the members and the work they complete is called teamwork.
Now, as for this game it means things like....covering a lead planes six so he can make the kill, giving check six, taking a position above the friendly on the kill to maneuver in on the other bad guys coming in for the easy pick....OR OMG maybe actually setting up a bandit for SOMEONE else to kill....what a concept...
FYI - Chickenwing = a comical game played by squad mates usuallying numbering 5 or more. When one member calls "chiiiiccccckkkkennnwinnnnnggg" all the other members try to steal his kill before he can get it himself. This usually results in hilarious howls of disgust and much smack talking among the squad mates.
