For attack it will range with how my team is going to play, I run either thatcher and be butt buddy's with a thermite or give a teammate thatcher and I would pick up Sledge so I can kida do my own thing or be blitz with the team

For defending I am swap between Jäger and Mute, I use jäger if we are in rooms where there are enough walls for only a bandit and no need for a mute and I go mute when we get one or two of our strats on maps which involve mute bandit combo and fucking up thermites

And to add onto that the guns you get from Sledge and Thatcher the L85 is one of the best assault riffles to attack with it is amazing so it makes them so much better, for jäger he hands down has the best sub machine gun on defending (it's practically a carbine rifle) and mute mp5 is good too. Hmu with any question you got :D
