What is this vehicle on Omaha beach?

[Noel Burgess]

That is an "Athey "Trailer - I believe there were two sizes but dont know anything about their use except that I also noticed them in the same picture. I have a copy of "Standard Military Vehicles" which has some data but it's in the bedroom , and "she who thinks she should be obeyed" has retired for the night - so maybe more info tomrrow
