Video shows the deployment of Cambodian T-55 (or Type-59) amid clashes with Thai forces.

Here are 2 easy ways to tell apart a T-54/55 or it's Chinese copy from other soviet tank designs:

•The T-55 has 5 roller wheels, like the T-62 (T-64, T-72, T-80, T-90 have 6, T-14 7). There is a gap between the first and second rollers.

•The T-54/55 is the only soviet-era tank with a bore evacuator placed on the very end of the gun.
