You're certainly using mid-range liberally.
A rapier would be considered close range, yes? I have to be with my arms length + sword length to hit you. For Ben that's roughly six feet (estimate). Sorta close-range?
Gokudera was considered mid range with bombs.

I say we need mid-range weaponry.
Whatever that would be. /shrug

[edit] Bolas?
Certainly a support weapon. Mid-range.
