Thank you for that. I can see how soldiers might count any tracked enemy armor as tanks. They didn't have any wargamer treadheads in the line.
Reading SLA Marshall's "The River and the Gauntlet" about the battle of the Chongchon River 1950, in the early phase of the Chinese intervention, the Chinese operated at night - no US air support. The US forces held high ground while the Chinese often flowed through low ground, infiltrating enemy positions. Chinese played bugles and sometimes flutes at night, causing nervous troops to open fire and give away their positions. US night fighting tactics improved later. And of course the Chinese had a massive numerical advantage in infantry.
By the time the 2nd Division had to retreat, Marshall says 10,000 Chinese were along the retreat route. That is the gauntlet part of the title.
A neighbor's uncle was captured in that retreat. He died in captivity. His remains were only returned in the last decade. My father-in-law served in the 2nd Division but fortunately in 1952. He came home to raise a family, including my wife.
