Like so many NATO member countries Canada has contributed significantly to Ukraine's defensive capabilities after the Russian invasion of the country in February 2022. This aid has so far included eight Leopard 2A4 MBTs, 39 brand-new Armoured Combat Support Vehicles, 208 Roshel Senator infantry mobility vehicles (IMVs), four M777 towed howitzers and 4600 anti-tank weapons. Canada was also the first nation to supply Ukraine with guided artillery rounds, with an unknown number of M982 Excalibur GPS-guided shells being sent for use with Western-supplied 155mm howitzers.
