The Colonel-Commissar - Support Grenadier Build
 Veteran Build - Warhammer 40k: Darktide 

Commissar Grenadier Build - "MEN OF TANITH... DO YOU WANT TO LIVE FOREVER?!"

Tanith burned once already. He's not planning on letting it happen to anyone standing next to him a second time....

• The Power Falchion -  Your very own sword of Heironymo Sondar. A versatile weapon for a range of engagements. push attack into overhead heavies is great for armor and single targets. Light into heavies does good horde clear but honestly light spam is damn viable below havoc games. Overload is an option for more energized uptime but i find i swap to bolt pistol too often turning it off and Wrath is great for a class that does not have any cleave in its melee talents.Try and blend in the occasional summary execution with the pistol to proc Agile Engagement and Weapons Specialist like a true commissar! 
• The Bolt Pistol -  Quick firing gun, perfect for specialists and gunners. Aim down sight just for a second to proc Deadshot to one shot most necessary targets, if not Puncture will finish anything bigger off with a mag dump. Constant cycling with One Motion Agile Engagement and Weapons Specialist gives you a versatile build and a bullet ever in the chamber with Always Prepared, never get caught reloading.
• The Ghosts Voice of Command - We aint just a commissar, we also a Colonel so with Duty and Honour Field Improvisation and Born Leader be Gaunt himself, the same discipline that held the line at Vervunhive! You could go full support with Covering Fire or Competitive Urge but I like to keep this build versatile, Gaunt led from the front, not the back.
• Kraks - Super boosted on this class with Lethal Proximity and Grenade Tinkerer with constant spares with Demolition Stockpile and Demolition Team, could swap to Shredders up to you, but krak's suits a regiment built on punching well above its weight in terms of bosses and armor.
