HMG, set it to lowest fire rate and tap fire headshots on hulks. 3-4 headshots is a kill.
Alternatively AMR, 2 headshots is a dead hulk.
Portable hellbomb for a free reset if heavies overwhelm you or if you need a bot drop cleared. Walking barrage for base clears. Autocannon sentry for fire support.
Normal ass liberator is fantastic for bots if you can headshot devastators BUT Scorcher is even better since the splash can allow you to kill tanks and turrets by hitting vents from the side of the turret.
Grenade pistol, senator, or talon secondary
Thermites

Only thing that should slow you down at that point is factory striders but you can kill them by firing HMG or AMR into their belly until they die, hellbomb them or throw all 3 thermites into their face.
