Korea calls her "Ram-G" because pronouncing LWMMG as a word is hard, apparently. Performs like a 4star. MK48 has the same skill as her, in case you want an upgrade later down the line. Good stats marred by low max ammo count. Probably more useful than most of the 3 star MGs.

She has a mod now, which you can see here

G43 is similar to M14 in night battles, but with a RoF skill instead of damage. Actually pretty good, suffers a little (ok a lot) in the day, but still better than nothing. At night however, very high RoF gives her a lot of nice things.

Tied for 3rd/4th place in HP out of all SMGs in all rarities. Has a stun bomb. You may find these useful if you badly need tanks in a hurry for some reason.

She has a mod, and that review is on this page

MURRICA. Usable but not as good as Nagant. Has a smoke bomb (unique among handguns) but the %s arent as high due to 2 star.

Her mod has a completely separate entry.

Very good buffs, not good in her own stats though. Skill is blah-ish but serviceable at night. When she gets to MOD3, however. Becomes COMMISSAR NAGANT. May or may not land you in jail (or gulag as the case may be). She does say it herself afterall, about your odd taste...

Her mod form is here

Generally decent buffs esp. at night, and she can be an evasion glass tank (100 evade!) in a pinch. Not bad if you actually kite your pistols but be wary of her limited HP. Honestly, you want a real tank in front still. Regardless, her buffs will see use even late game, for example support M4A1 MOD3.

Her unique expedition equip is decent (even more evasion), but not strictly necessary, she's already good enough without it.
