OBEY. Made from a less-lethal shotgun meant to give police forces more options to put down people without killing them. In G&K's case, however, she certainly helps with takedowns.

Incredibly good stats for a shotgun, good formation buffs, and her skill has the unique ability to cancel enemy buffs. These buffs include ENEMY SHIELDS (including Patroller shields) and stat buffs (including bullshit enemy evasion buffs). Her mechanics are unique, so she actually ignores normal knockback immunity. Oh, and her armor buff stacks are multiplicative. Unfortunately, the Minotaur's damage reduction is a weird thing that can't be removed, but regardless, you get so much utility from her. Even if you don't need her skill, her stats are just that good.

If you don't have her, get her from a True Core Mask or something. She's just too useful in things like later Theater events.
