Why gunbreaker?

[Cabalabob]

I was just thinking about it today, gunbreaker is a really odd name. Gun obviously comes from using a gunblade, but why breaker?

It honestly makes me wonder if the name is the same in other languages or if this is another case of the localisation team trying to be creative (is it actually gunblader and they just thought that sounds stupid?).

I feel like there are much better names they could have gone with, maybe something like magitek knight, the gunblade looks like it’s going to be a magitek based weapon, much like the machinist guns, using aetherially charged cartridges to power the weapon. And one of the inspirations for the job is Seifer from ff8 who always dreamed of becoming a knight.
Or maybe mercenary, since again the job is based on Seifer and squall who were members of the mercenary group SEED.

I just don’t see how they decided on gunbreaker for the name, it’s not like it’s going to be some anti-ranged tank that goes around smashing peoples guns. I just wonder where that choice came from.
