2.5-4% Bonus Critical Chance on Chained Hit. Stacks 5 times.

Be Rambo. Fire at will.
This build is made to stay in 3/4 syntony with your allies.
Spam "Voice of Command" when ready in combat.
Use grenades on packs of armoured ennemies or crushers. Which are the only ennemy you'll struggle to kill.
You can survive quite nicely alone but will get overrun as you run out of ammo and take some damage when having to reload.
Could swap "Vanguard" to "Deadshot" if it suits more your playstyle.
Focus priorities : Flamers, Shotgunners, Mutants, Reapers, anything armoured (except crusher).
Just dodge Dogs and let your team kill them while you tear down any group of ennemies coming at your group.
Works best in my experience with : Survivalist Veteran, Crowd control or sniper Psyker, Butcher Ogryn.
And you could also swap melee for anything else you prefer, keep in mind to have a weapon with both good dmg and good cleave. And not too slow or you'll get overrun. aka no knife, no big axe.
Weaknesses : Teamplay reliant ; Can't efficiently kill snipers
