CAPTAIN CHINNNAAAAA! Surprisingly good for a free unit. Has the lowest armor among the shotguns (tied with Super Shorty), but she will get you started considering how easy it is to get her. Aura optimized for 1SG/1HG/3MG setups, and works well with Mk23 and M2HB (which are both given for free to new players too). Has a very tiny 3-shot magazine compared to the usual 4 most SGs get which limits her firepower somewhat, but her skill offsets this a bit. A flawed unit and not a first pick for many lineups, but most SGs are interchangeable as far as front-row tanks go anyway, even if she's not as good at it as the other ones you'll get eventually. Her main merits are a decent aura shape and being free.

She does have a mod which...kinda makes her better? Will add that article soon...probably.
