I'm not so sure about the 5.11 I can tell you what I used on my tank tho. Chill out mask 2 pfe mods Everyday carrier chest explosive resist, armor regen pfe mod Uzina backpack with adrenaline rush explosive resist, regen and pfe mod Generic holster and gloves both with armor regen, explosive resist and pfe mods And here's the ace part Sawyers kneepads for the explosive stagger resist. Lullaby shotgun and a big boy shield.
There is sooooo many explosive drones, grenadiers and warhounds this allows Sawyers to shine, 30k ish regen, 70% explosive resist 77% pfe and 2 mil armor. Just eat the explosives.
This worked for me, you don't need a 100% copy but explosive resist and pfe with Sawyers is really strong here
