First of all, it says destroy 5 Equipment, Field Upgrades or Scorestreaks, Both Equipment and Field Upgrades apparently don’t even work, so that just leaves Scorestreaks, which you can only really get in Plunder (Hell). So that leaves Counter UAVs, SAM and Sentry Turrets, the latter almost never get launched and Counter UAVs you cannot get to 5 in time and destroy them all with a launcher that doesn’t lock on. Infuriating stuff.
