The Trooper Squad is the base squad available to each faction, and each faction can relatively kit them out to their heart’s content. Though for some who choose to try and make their squads semi-historical, like myself it is not a boon to have to choose between an Assaulter or Gunner for a Squad when a Squad had one of each in the Squad Gunner and the Squad Leader. I would suggest that the Gunner and Assaulter options be split into two different mutually exclusive branches on the tree. Though, if it has been set for balance, that Assaulters and Gunners may not coexist in a Squad, then simply ignore this suggestion.
