Sure it's more probable, than flamethrower tanks... I only doubt, if they were available since 1946. Unfortunately, there's no info anywhere when BTU (basic model) was developed. I'd guess some 1949-50 or later...
Edit: there is one photo of Polish T-34/76 dozer in Magnuski's book - the one used in the game.
