Having fun with my current assault troll loadout.
Loadout:
Model 10 hunter
(any pistol you like)
AT rocket gun
AT mines
gas grenades
(any melee).
You can storm any building or trench by lobbing in the gas grenades and then going in fast with the shotgun. Occupants will be forced to either flee/don GM or die. Shotgun works best for hip fire anyway.
AT mines to be left somewhere tanks are very likely to go, but make sure they're in a shadow or shell scrape to give them a better chance (Put some just to the left of a gate in a wall last night on D flag (St Q's Scar), pretty sure a tank would burst through the wall there and low and behold 5 bang.)
Counter sniping snipers with the AT rocket is much fun, apparently they can be used against vehicles too!
