Very fun build using only Veteran-unique weapons.
MK1 Shovel gets buffed by Hotshot on Helbore and improves its cleave. If you prefer to play more of a backline sniper, get Weight of Fire instead.
Surgical Helbore with Shock Trooper is incredibly ammo efficient and essentially doesn't need any ammo pick ups. Therefore, Survivalist is not required and you can take Fire Team with Grenade Tinkerer instead.
VoC would naturally be more meta than Infiltrate. However, Infiltrate with Low Profile is still great to quickly dispatch distant specials and gunners without having to worry too much about a horde close to you. Note: Don't use Infiltrate to run away from your team. Use it to drop aggro to quickly take care of threats.
I prefer 2*Sprint Efficiency on curios because neither Shovel (+0.27) or Helbore (+0) have great running speed, so you are a bit more mobile. However, they can be exchanged for any of the following: Toughness, Health, Gunner Resistance.
