At the outbreak of the war , MAG - 33 was part of the 1st Marine Aircraft Wing ( 1st MAW ) and located at Marine Corps Air Station El Toro , California . The group was well below normal strength due to force cuts which came after World War II . Because it was a skeleton of itself , the majority of 1st MAW had to be stripped bare to reconstitute the MAG . Air group personnel and equipment boarded the transport USS General A . E . Anderson ( AP - 111 ) and the attack cargo ship USS Achernar ( AKA - 53 ) at Terminal Island ; aircraft and aircrews were embarked on USS Badoeng Strait ( CVE - 116 ) .
