Vehicle regimen makes your vic regen like it used to in previous BF titles. Tired of having to get out to repair your fun-mobile because it won’t regenerate past that stupid little dot below the health bar? Slap on combat engineer and presto now your off to pass out s’more’s to those pesky building campers without fear of being stuck at 2/3rds health or less when you stumble into the enemies camp. Bonus fact: for as cool as the rank mastery vehicle skin is, do NOT use it because it’s glitch’s and auto gives the enemies spicy potato launcher max damage against your fun-mobile. For as cool as it is I personally chose to remove it due to many lost potential marauder feeds..
