One thing I have noted on the M-4's is the different grouser plates used for different AOO's.
As these ones appear to be all steel without the rubber blocks and wider whereas in the PTOO's they have a cleated design to go over the reefs and in ETO they had the blocks and extra cleats attached to the outside of the grouser plates for grip in the muddy conditions. A nice picture this one.
I gather they are following another tank in front ensuring to walk in the tank tracks.
