References from the MSBS Grot Wiki and the manufacturer for the Promet.
References from various sources and Wikis for the AK15 variants (AK12 chambered in 7.62x39 mm).

English first for string tables?

Move English to first position in stringtable. We forgo the second English entry Original, because it is a duplicate, however, this means the first language is the fall back if the game language is missing.
Therefore English should be at first position.

English first in stringtable

Might wanna include info about the cartridge in the names for the MSBSs, as this is not the standard 5.56 variant. The older naming system described on the wiki seem to allow that already, otherwise just drop a (6.5x39) on them.

MSBS-6.5B GL
Grot B20PSBI-M2 (6.5x39)

Something along those lines.

Maybe should be like that but, for example,
the Promet Marksman 3D model is a bullpup version with a 22" barrel which doesn't exist.
The real one is chambered in 7.62x51 and looks like that : MSBS DMR rifle

So, an exact designation with a wrong caliber has no sens imo, as many rifles in this game.
The reason i chosen a compromise with the BI and the manufacturer names.

• All English entries first fixed.
• Contact pistol and launcher added.
• Minors updates.
