I read with amusement the story in the blog of the cc platoon running around with hammers at the port. Back in 1972 (old corps)as a Huey pilot with HML-267 I had occasion to transport a general to MCRD. We landed at San Diego Linberg field where the Gen. Was met by a staff car and we settled in to wait. We were about a half mile from the fence and could hear a resounding "thump"coming from the depot. We walked over to the control tower, and from the cab we could see into MCRD. We could see 20 to 30 Marines standing around an old Quonset hut slab each with his hammer at the port. The D.I. Was standing in the center of the slab calling out the cadence. "Present Hammers" "Ready too". The mystery of the "thumps" was solved. J.M."Mike"Jeffries Capt. USMC Ret.
