Polish Army KTO Rosomak-M1M

Polish Army KTO Rosomak-M1M in Afghanistan

During the war in Afghanistan the KTO Rosomark was fitted with initially fitted with additional steel-composite armor, upgraded communications, wire cutters in front of driver and commander hatch, external video cameras for improved Situational Awareness and the Pilar system for directional detection of incoming fire. Because of additional armor this variant cannot float and has no water propellers.

This variant was further upgraded to the KTO Rosomak-M1M, which had QinetiQ RPGNet for defeating Taliban RPG attacks and a new sand camouflage. The new nets proved effective during attacks and offered the added bonus of being lighter compared to Bar armor, thus offering better mobility.

The Rosomak was also deployed with Polish Land Forces as part of the EUFOR Tchad/RCA mission to Chad.
