While watching a TV show called Eté 44 (summer 44) about the french liberation I was stunned to see in a short color sequence about the landings what seems to me to be an LVT-2.
Sometimes those documentaries are made of mixed and match pictures or movies so you can see US Marines langings to illustrate the Normandy campaign but this time it doesn't seem to be. (that's why I have included other pics of the same sequence)
I've never heard before that LVT had been used on D-Day or the days after because the scene looks rather "peacefull".

Additionnal note: after a second look the barechested man on the first pic makes me think that these are again mixed pictures.
