i know this is a reach, but who knows. In 1972 in the Freedom Hill complex, home of the 196th LIB, I saw several M728 Combat Engineer Vehicles. The Engineer company for the 196th was the 175th Engineer company, so they might have been theirs. Not knowing I'd be building a model of one 50 years later, I took no pictures. Does anyone have any information on markings for these CEV's or any others from Vietnam? The few photos I've found on the internet show completely different markings for each vehicle.
