I was playing in a single-player Co-Op when I noticed issues with the primary infantry weapon for both Germany and USA, although they aren't the same problem (so if it is an intentional mechanic, it'd be great to know)
For the M1 Garand, you cannot reload mid-clip (you fire a few shots, hit R and it doesn't reload) and instead automatically reload when you fire off the last bullet in the clip, a feature not present in any other weapon in the game that I know of.
For the K98, you cannot perform an estimate on how many rounds are left (holding down Q to bring up the communication rose and looking at the lower right portion of the screen shows nothing aside from the usual clip counter).
