Defend was a mission objective which involved guarding a stationary capital ship, base or jump point. Fighters were required to orbit the position at 2,500 meters and not to engage attackers until they were within 5,000 meters of the object being defended. It was discussed in Taggart's Tactics. It was one of five mission types which comprised 98% of flight missions flown off the TCS Tiger's Claw.
