Veteran
7.5-15% Weak Spot Damage. Weakspot Kills also ignore Enemy Hit Mass.
Hitting an enemy gives them 1-4 stacks of 2.5% Brittleness. Debuff lasts for 5 seconds and can have a maximum of 16 stacks.
5-6.5% Strength for 3.5s on Close Range Kill.
Strictly close quarter veteran build, it provides tankiness for the team thanks to the short cooldown on Voice of Command + the further cooldown reduction from Tactical Awarness. Because you can keep your Toughness higher for Longer, Iron Will stays active for longer giving a nice 50% damage reduction, and the frequent triggers of your ability synergies with Close Quarters Killzone for a reliable +30% damage at close range.
Both weapons can be changed depending on preference, I like the Antax Combat Axe most for this build; and either a Brace Autogun, Shredder Pistol, Laspistol or an IAG of some description are perfectly fine subsitutes if you don't like shotguns as your close-in ranged option. Pistols for speed, Laspistol for better long-mid ranged performance and the IAG/Braced Autogun for superior hordeclear and suppression.
Untested for Damnation difficulty.
