Sounds little strange to me.....seems to me the Abrahms should be bigger. See if you can find any real photos of humvees next to Abrahms tanks and eyeball it. Or, if you know the acutual dimentions of a real M1A1, do this: Grab your calculator, then take the actual length of the tank in feet and times it by 12. This converts the length to inches. Then, divide the length in inches by the scale of your model, say 35 for 1/35 scale. The number you get should be the approximate length of an M1A1 in 1/35 scale in inches. Now, measure your kit and see if the numbers match. If your tank is a few inches smaller, it's probably a 1/48 scale kit. You can do the same process over again and divide by 48 (for 1/48 scale) and see if that comes out to the length of your kit.
