Tips & Counters
Bradley stops regenerating health once you land the first hit, but it heals back to full over 60 seconds if you go 5 minutes without damaging it again — commit once you start, don't trickle damage in over a long fight.
HV Rocket is cheapest by sulfur, but C4 goes through it faster (10s vs 24s to place) — worth the extra sulfur if the base is online and you need to be in and out.
