Tactical Air Control Party (TACP) Practice Test

A 500-pound JDAM variant with low collateral damage and reduced explosive fill is designed to minimize the blast and fragmentation footprint while still delivering precise guidance. The variant built for that LCD purpose is the GBU-38v4. It preserves GPS/INS guidance for accuracy but uses a reduced explosive fill to limit collateral damage, which is exactly what the question describes. The other options refer to different families or configurations (laser-guided or smaller diameter bombs) and do not emphasize the reduced fill for collateral damage.
