I bought this one as a built model. I don't collect many soviet tanks but, I thought it was unique with the Romanian markings and the blade on the front.
T-55 tanks have been equipped with the BTU dozer blade for use within tank units requiring specialized engineer support. The tank dozers accompany the armored vehicles and are used to neutralize obstacles while under fire. The BTU dozer blade can be mounted in 90 minutes and dismounted in 60 minutes.
