A lot of times I hear.
Opponent, "I'm shooting at that squad."
Me, "What squad there are three in that building."
Opponent,"Oh, well...er.."
Me, "Ok ther are two on the second floor and one on the ground floor"
Oppenent, "The one with the taleran guy.."
Me, "both on the top floor have some talerans."
Opponent, "The one with the three auto cannons."
Me, "Ok"... thinking why didn't he just say so from the start...
Me, "Darn you killed a loader..."
My cadians have numbers on their shoulder padds for the different squads. My catachans are mostly my more elite squads. And the valhallins and talerans are mostly fire support squads with heavy weapons. But it does get confising, that is why I paint each platoon slightly different and have different numbers on the guys for each squad they are in.
