Canada buys Dutch Leopards
"I've found some additional information. It looks like the Canadian purchased 20 Leopard 2A6 and 80 2A4's.The latter will be rebuild to 2A6(M?) standard. The 2A6 vehicles will be converted to 2A6M standard, with as soon as possible deployment to Afghanistan in mind. I guess Dutch type smoke grenade launchers and such will be replaced with Canadian standard equipment.
The 2A4 tanks are in climate controlled storage, the 2A6's seems to be pulled from operational Dutch units.
So the Canadian armed forces will make a quantum leap in armoured capabilities."
