This is a map tactic on Thunderbolt.
3 vs 3
Start off point is 1 assault, 1 medic, and 1 lancer that is FC.
At this point if you see the team is double medding than we 2 med. 1 med take and other stays with FC at all time. And 1 becomes a lance. The lancer is the meat shield and killed the med.
4 vs 4 and 5 vs 5
Is the the same 3 vs 3 but you double the method.
