Having trouble with a Scarab? Or maybe you don't want to get on board (and abandon your bright, shiny Scorpion). Try this strategy instead: on the back of every Scarab, there is a circular glowing spot you can shoot to do damage (it is similar to the glowing spot on the back of Wraiths).

Locate the spot on the Scarab's rear armor that is below its rotating anti-air "ass" (or abdomen) turret. A few shots from Hornet missiles or Scorpion tank shells and the armor will fall off and reveal the critical system you normally need to board to wreck. Don't forget that shooting the Scarab's legs will stop it from turning.
