I tested ALL BOOSTERS in HELLDIVERS 2 so you don't have to

Reinforcement Budget added four starting reinforcements; Flexible Reinforcement Budget reduced cooldown from two minutes to 1:47. UAV Recon seemed useless on spores but improved enemy visibility and radar indicators on clear terrain. Stamina added roughly three sprinting seconds; Muscle helped bush traversal, while Vitality and Hellpod benefits seemed inconclusive or obvious.

Rushed re-tests and software failure produced practical but partly uncertain booster conclusions.
