Beat me to it... The M-1 is most certainly not an M-14, even though they are related.
I am more concerned with those 8th and I Marines sloppy carriage of the rifles: There isn't a parallel line among those muzzles and the Color Guard in the photo looks like he has his rifle wrapped around his neck. I would not have put up with that level of drill proficiency when I was still in and the Gunny would have had some extra practice for those Marines.
They are looking a little shabby, but I could hardly blame them though based on the situation.
Their current CiC hates them more than even PDiC (Pants Dropper in Chief) clinton ever did.
When PDiC visited Baumholder Germany before the start of Operation Neverending Balkan Excursion (IFOR/SFOR) the M2A2 Bradley on display at the back of the parking lot where we were assembled didn’t have the coax installed, and the bolt was removed from the Bushmaster. The M1A1 Abrams also on display was stripped of it’s weapons and the main gun was rendered safe. We didn’t have weapons either.
I guess the giant sign near the main entrance that said “Welcome home draft dodger” really pissed him off especially since it was on private property. :D
