An OP should have a little more discussion; it should at least clarify the subject a little, and preferably offer some ideas or suggestions of your own, etc. Simply stating the subject and then leaving the post blank seems questionable to me.
Anyway, if what you are asking is what if the Bay of Pigs invasion used US troops (and in retrospect it is clear they would have to be used if the invasion were to succeed; air power would not be enough and the anti-Castro revolt in the cities that was hoped for was not likely to materialize), see my post at
