Semper Fidelis to all US Marines past and present!
I served in the Corps 6/64 - 3/68, Vietnam 7/65 - 3/67. Back then there were a few WW II and pre-WW II Marines still on active duty. The old salts often said/complained the 1960's Corps was not like the pre-WW II and WW II "Old Corps." Later, I heard this ditty and often think of it, my experiences, and those I served with:
The Old Corps!
The Old Corps, the Old Corps, the Old Corps
That’s all I ever heard about!
But as Tun’s fist Marine sneered when the second appeared
“It’s not like it was back in the Old Corps!”
