Refresher students are Fleet Marine Force Aviators returning from shore duty billets or military schools.

Based at Marine Corps Air Station Camp Pendleton, California, HMLAT-303 conducts an extensive training syllabus to include: familiarization, navigation, ordnance, terrain, formation, instrument and night vision goggle flight.

The squadron periodically deploys to Marine Corps Air Station Yuma, Arizona, where training efficiency is enhanced due to the proximity of ordnance delivery ranges and superb weather conditions.

HMLAT-303 trained AH-1W Cobra and UH-1N Huey pilots for the Marine Corps and Navy for more than 20 years, until both platforms were upgraded to the new AH-1Z Viper and UH-1Y Venom.

HMLAT-303 is the only Marine Corps squadron tasked with training UH-1Y and AH-1Z replacement, refresher, and conversion pilots and aircrew.
