By "Ground Snipe" do you mean that you run with a Sniper Rifle? if so that's definately a tactic i've never considered. I buff my suit with Enhanced Shield Extenders since the Armor Plates slow me down and make me sniper fodder.

If you don't mind me asking, how often do you die? And how far away do you stay from your squad? It seems in that case i can see the upside of being farther back to avoid direct contact with the enemy and sniper fire isn't as troublesome since you can fire back. I like to stay as close as possible to my squad, or Blue's if my squad leader doesn't have a mic and doesn't lay down directions, so that i can heal and support them as effectively as possible. So i'm curoius as to the tactics developed by other Logistics. Maybe when it comes down to it, it's just the advantage of being in a Corporation.
