Deflector Shields used offensively.
Deflector Shields and Some Kind of Force Field in general make great defenses, yet apparently some people don't know that and keep using them as weapons--and what do you know, it works. Sometimes, the forcefield may incinerate anything that touches it; another possibility is turning on the shields and ramming the enemy without fear of your vehicle being damaged in the process. In any case, an aspiring combatant can try to use the Attack Forcefield by activating it while an enemy is near, or by activating it and rushing the enemy. Shield Bash is the low-tech equivalent.
