Sniper for alpha strike, smg for mid/close i personally dislike melee weapons.
Tbh solo smg would work too!
Right, but why give all of your members identical weapon skills? Wouldn't it be more economical to have, say, 2 AR, and 1 snipers and 1 energy? If it's because you have a skill glut, I don't see any tactical benefit of a 4X AR/Energy team, whereas 4XAR/Sniper would be an interesting configuration, allowing you to change your composition depending on the terrain. I.e. if you have melee running towards you from a distance, sit back with 4 snipers. 4XAR for more cqb, etc?
