Universal:

This class is meant to be a jack of all trades, typically what I bring out first to see what I'm dealing with.

Loadout:
Scar-H, Shotgun - primary
Stinger - secondary
Blast shield + Stun grenade
Scavenger
Stopping Power
Steady Aim

Scar-H is underrated, but for one big reason that is overlooked. The sights are extremely small with a fine point, essentially making it better than a red dot. It barely has any recoil and it punches harder than you need anyhow The shotgun is a good attachment when running a rocket launcher, it can one shot in narrow corridors, but only with stopping power + steady aim. Scavenger is optional, it can be swapped with whatever you prefer. I tend to try to live a while with this class and shoot down score streaks with the stinger.


D. Marksman:

This class bring universal and sniper together, good for engaging at any distance and being a mobile sniper.
M21 EBR, Acog - Primary
Desrt Eagle, Akimbo - Secondary
Tactical Insertion + Flash Grenade
Sleight of Hand
Cold Blooded
Ninja

The M21 looks like garbage upon reading its stats, but there is one thing not covered by stats; Recoil. With the low recoil, you can either aim for a moment and line up headshot, or if somebody is closer, triple click like a burst weapon. And if somebody suprises you up close, you still have a chance to spray. Dual wielded desert eagles can do massive damage up close, the m21 has little ammo, so if you run out or if you hear somebody close, handguns have the quickest draw time. I chose Flash Grenades over concussion because they have much wider radius, better suited for entering buildings. Cold blooded and Ninja let you stay mobile without getting spotted as easily.

Rust:

I made this class for the exact reason you think. Rust is ♥♥♥♥♥♥♥ crazy and you may as well feel like a badass.

Loadout:
Riot Shield - primary
Desert Eagle, Akimbo - secondary
Blast Shield + Stun Grenade
Sleight of Hand
Stopping Power
Steady Aim

Pull out your desert eagles and go guns blazin' into the cramped middle section, enjoy not getting shot in the back and mow them down.
