Navy vs. the Marines, as ever

Rico says his friend Tex (a former Marine) sends this:

A Marine and a sailor were in the bar, arguing over which was the superior service.
After a swig of beer, the Marine said:"We had Iwo Jima."
Arching his eyebrows, the sailor said: "We had the Battle of Midway."
The Marine nodded. "But some of those pilots were Marines. Henderson Field on Guadalcanal was named after a Marine pilot killed at the Battle of Midway."
Taken aback, the sailor said, "Point taken."
Then the Marine added: "We were born at Tun Tavern."
The sailor replied:"We had John Paul Jones."
The argument continued, until the sailor came up with what he thought was surely the topper: "The Navy invented sex."
The Marine didn't blink. "Well, that may be true," he said, "but the Marines started having it with women."
