Need a build for heavy gunner on Supreme Jerk

[Matt [Reckless Boi]]

My heavy gunner is quite decent. However it's not good enough for Supreme jerk, in fact she barely kills anyone and I tend to mostly use her as a rocket launcher station, without using the Lmg much, as it hardly ever has a chance to hit higher than 35-40%.

Is there a build that's the facto the best for heavy gunner?

For gunner cordination, awareness and int is most important, You probably have explosive skill and in Aspen You find a lmg with explosive ammo, later You can modify minigun with explosive ammo, +20 Damage barrel and -1 ap to fire mag, then You can shoot 2 times per turn with the minigun.

Late game heavy gunners suddenly become strong. Modded minigun is a meat grinder on Supreme Jerk. Guns before that, not so much... Early and mid game machine guns kinda just are mediocre, so you might as well keep the heavy gunner a support character at the same time, giving leadership to him so that even if he doesnt kill he adds to the team. Rocket launchers, which are explosive weapons and not heavy guns, are great all the way through though, but ammo is expensive if you dont abuse antique perk.

I made hybrid flamethrower build with disciple of metal and pyromaniac.
Big Guns explosive, toaster (for fire damage) and weird sience ( fire damage) really good damage with flamethrower and You can also use chemtek armor in midgame with inbuilt combat stim. +2 ap and 15 AIM which he really helps with lmg:s poor accuraccy.
