My Father worked at Eglin for nearly 30 years, and my Sister worked as a secretary at Hurlburt before going to college.
I remember around 1960 there was always a bunch of A26 bombers with machine guns sticking out the nose parked around the base. Also a bunch of Cubans.
I remember one time my sister brought home her date. He was a Cuban from Hurlburt and apparently the hottest thing on the base. My Mother pitched a fit and told her she was not dating any more foreigners, and she didn't. The funny thing is, he was very well mannered and could have passed for an American, until he spoke.
A "commando" otherwise means a small-to-middling sized military GROUP, larger than a platoon, say perhaps a hundred to a few hundred men, operating on its own [at the moment] rather than as part of a larger army.
