So if it hasn't been said enough, absolutely get the Mod1 the very second you can. It's 200 fragments and some cores for a fair boost in performance. Extra stats, a bit more FP buff on her tiles, a little extra HP, and an improvement to the slowdown effect on the smoke.

The real problem is her 2nd skill is janky and not extremely practical. It's a little bit of a bonus, but not likely to make or break a fight. So yeah, the Mod2 isn't great. The mod 3 however, gives her a unique equipment that goes in the suppressor slot and is basically a suppressor with better stats (+5 EVA over normal) which helps her tanking ability somewhat. Whether this is worth it up to you, but definitely get the Mod1 at least.

The rest of this is basically the same song and dance where she has top class offensive buffs that continue to remain unmatched among SMGs, so you WILL likely continue to use her.

Thot Twin #1

Honestly, what you should be looking for in a beginning tank SMG. Decent HP pool, good dodge, a smoke grenade that slows enemies, good aura to support an AR squad, really the standard to which you'll hold early tanks to. Overall, probably the best to have for general use until you get RO635 mod.

If you want more info on her mod, look at her mod article.

Not to be confused with PP-19. Like all smoke grenade SMGs not named UMP45, she suffers from the fact that UMP45 exists. Or more pertinently, now that RO mod exists. Basically a cross between UMP45 and UMP9, she uses the same smoke grenade stats and having slightly less evasion and slightly more HP she's about as good at tanking, but her buff tiles are awful compared to UMP45's.

In older times she was an alright choice back when there weren't as many SMGs, but these days you should have more choices and if you REALLY need a smoke, Ingram (especially now that you get a free one) can probably tide you over until you get UMP45.

Modded version of M1911

A really expensive trash cleaner.

Basically when she pops smoke, she then goes Alvin York and blasts away 7 times for extra damage, hitting the farthest enemy and working her way closer to the front with every shot. If there are no closer enemies, she just keeps shooting that one until someone else has gotten closer (either because its dead and thus a new thing is closer, or something ran ahead of it).

Note that while the skill has an ICD of 1 second, she doesn't actually start blasting away until 3 seconds in due to the throw animation.

Good buff, but honestly kinda shit for most purposes (but her buff tiles are better than Sten's if you somehow happen into a pile of her early). You want a better SMG, honestly, but if you're desperate sure? Mostly cores though.

Her exclusive equipment is a silencer, and while it gives ten more evade over a regular silencer, is expensive as all hell and doesn't give her a significant boost. It does make her a bit more on par with UMP45's base stats, but with significantly worse tiles.

She has a stupidly big HP pool, but otherwise her stats are more 2½ star than 3 star. Combine that with a decidedly average smoke grenade and terrible tiles, and you end up with a doll more bland than Foster's. Can be made work if you really want to (give her plenty of evasive buffs), but you're almost guaranteed to be better off with UMP45 if you want smokes.

Combine an MP40 with an MP28 lower and you get a gun that's more expensive to build than an MP40 without being any better. Thanks Schmeisser, real good use of limited wartime production capacity.

…in-game, she's a 3* smoke grenade main tank and at best a sidegrade to MAC-10 with worse tiles and roughly equal tanking capabilities (less evasion, more HP).

Both are worse than UMP45, and Ingram is cheaper to raise, so there's no point in bothering with MP41.

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.

AKA Swedish K, aka m45 aka the REAL bakery girl, aka CINNAMON ROLLS AGAIN!? 2 star smoke grenadier. If, for some reason, you're doing a 2 star challenge she's cheap and the smoke helps (and she badly needs it because her stats otherwise are pretty low). Otherwise you really, REALLY should be working on getting UMP45 or something instead.
