What kind of military truck is this? The photo is tagged “M705 1.5t Chevrolet Truck”, which I do not think is correct. Or is it? Anyone have more information?

What is it?

What is the scoop with this tank truck? Were the tracks supposed to drop down when it got to rough or muddy for the tires? What kind of truck is it?

Hard for me to tell, but is this a Dodge Power Wagon or one of the larger Chevrolet trucks?
