Oh dear, that old furphy that CMPs can actually become
bogged ....
Careful research, including personal interviews with various of the military personnel visible in some of the images, reveals that, due to the inability of service personnel to incapacitate and prevent forward motion of CMPs by driving into rivers and areas of muddy ground known to bog other vehicle types (GMCs, Dodges, jeeps ...), it became a wide-spread practice to stage simulated bogging events whenever a photographer appeared. The aim, as revealed by the pranksters themselves,was to deceive those future generations of military vehicle enthusiasts who express such enthusiasm for other than the mighty, unstoppable CMP!!
Duck .... incoming!
