I though vigilante armor very weak? One rocket gg alr
use speed, both move toward each other, mk2 will lock on you first and fire usually 2 missile, as vigilante drive closer about 1sec later vigilante will lock on to mk2 and fire 1 single missile
then mk2 missle will move towards you and vigilante use booster. usually those missle got no time react and will hit the road as it tracking is poor. as compare to vigilante which have one of the game best tracking even mk2 flare is useless. so 1 missle will do it
next, if they use chaff, same thing but this time use booster to drive pass at high speed as they will lock on and fire missile first.
once you near them, do a 180turn (about 2 sec) and then vigilante will lock on as chaff block the front and not his back and fire missle.
3rd using booster and rush towards them as fast as you can and just fire at them and most like they will hit you but mk2 got 5min to wait which mean even if they hit you, mk2 got a 5min cooldown after it destroys where vigilante have 0min cooldown after it destroy but after that the cooldown is 2min count down then back to 0min again. after a few time they give up because of the 5min cooldown but of course not many know they can go to their garage to get mk2 without waiting for 5min
