Have the United States ever actually given direct military support to an Israeli operation or visa versa.?

Despite the enduring and very close diplomatic and military relationship between the United States and Israel, and all the indirect aid (funds, supplies, weapons etc.) the United States has given to Israel, it has occurred to me that I do not know of a single instance in which the United States actually lent troops or direct military action to an Israeli military operation or visa versa. Is it true that such has never happened?
