The Leopard 2A4M CAN is the upgraded Canadian version of the Leopard 2A4 acquired from the Royal Netherlands Army surplus. The Leopard 2A4M CAN is specially designed for the war in Afghanistan, based on experience gained by Leopard 2 operators. The first 20 were delivered in October 2010 and with only 5 being deployed to Afghanistan at end of 2010, and operated until July 2011 when combat operations stopped. Though originally planned to be up-gunned to the L55 for consistency with the 2A6M CAN, the longer barreled guns were found to be less than ideal in Afghanistan, therefore it was decided to retain the L44. In addition, only small areas of slat armour were added, in contrast with the fully caged 2A6M CANs. The protection of the Leopard 2A4M CAN has been further augmented with the addition of applique armour resembling that found on the most recent Leopard 2A7+ variant, but modified to fit the turret configuration of the 2A4.
