I think I'd speak for all of us that are playing regularly together that anyone, with any play style, is welcome to come in! We almost always make a plan of some sort, with equal input, and cheerily go forth with whomever throws out the first idea. We are quite egalitarian in our killing sprees, I'd say.
There have been some sublime moments thus far, taking down entire bases with almost no EI (enemy infantry) shots coming our way. Then there's the 'best laid plans' where everything goes nuts, silencers come off, and we tear into, and get torn up. Some missions or situations are just written that way, with mass destruction and cartoonish amounts of enemies.
MBS, we frequently switch up tactics, often to get those extra skill points! Whatever tactical role you'd choose can be made good use of. I've ended up with a sniper rifle (not a DMR), and every skill possible to buff it's use. I just need some high-end weapon parts and I'll have topped out my Sniper weapon buffs. Now I'm using solo time to practice my first-shot kills, kills while EI is on the move, mil dot distances, that sort of thing. Furthest kill thus far is 502m, whoop
Being up above and giving overwatch to my team just feels amazing sometimes. The teamwork is everything I love about playing this game.
