What weapon would you choose, and why you chose it. Lets keep it realistic.
1. Close quarters combat............E.g, Clearing a small room
2. Ranged..........E.g, A auditoorium
3. Sniper............E.g, 300 yards or greater
It would be different depending on the situation!
I always carry a melee weapon! Because i trust my fellow citizens :)
I'd use a ranged one for more serious business :)
Otherwise, both melee or ranged can work, depends on the flavor at the time.
A sniper is expensive, if you buy me one i will love you forever! <3
