Why would MIR be on the side of a combat vehicle? (Score 2, Interesting)

The designation 'MNP-2' can be seen on the side of the booster rockets in some of the photos. MNP is the Russian 'Mir', or 'peace'. Why would 'peace' be on this machinery? Sarcasm? Camoflauge? (after all, you would expect something like 'KillBot' on the side of a combat vehicle) Simple re-use of boosters from the Mir program? Or maybe hoax? ;-)
