Just a small nitpick, but I feel that weapons like the SIG 1920 and the S1-100 should have their Japanese names, rather than just having the Western names. The SIG should be renamed to the Type Be, and the S1-100 should be renamed to Type Su. I just feel like it would make more sense this way, and they could just have the western names in the descriptions of the weapons.
Not sure if there are any other weapons with similar issues, but I think that in general it makes more sense to use the official designations of whichever nation’s tech tree the weapon is in.
