The Sikfrit Model 54 can be used by either team.
But it hits like a truck. It has a high anti-vehicle modifier compared to most other small arms, and can penetrate metal by twice as far.
And if that wasn't enough, it's costs are virtually none. If you've got a free weapon slot in your loadout, a Model 54 is never a bad call.
