Hehe I also used to spend quite a lot of time renaming troops in a way that pleased me.
That way, I could "emulate" a better hierarchy structure, with names starting by Team Name (like Alpha, Bravo, Charlie according to their overall level), and function in the Team. I ended up with names like :
Alpha/Team Leader
Alpha/Sniper
Alpha/Medic
etc...
Quite useful, actually
I mean, beside being funny :p
