I actually had a bit of a look around on-line for 1/72 LVT's and Amtracs but so far I have only seen the 1/35 kits . There are a few pic's in my books of Marine LVt's and Amtracs
hooting that Quad .50 must have shaken the hell out the chassie on the M-16 , I can only imagine how bad the vibration must have been .
