Right.
It's not my place to comment on future policy options that the Government of Canada may or may not be studying. However, I will bring up the issue of cooling, which you quite correctly have identified. A lot of the kit we have in the Canadian army is absolutely first-rate; it really is.
The Leopard tanks that we're currently using in Afghanistan are in excess of 30 years old. We spent a great deal of money getting them fixed up over the last 10 or 15 years, but the current Leopard has some vulnerabilities. You will forgive me if I don't go into details. I trust you, but I don't necessarily trust....
Concerning the cooling system, it is projected that by the middle of the summer, the inside temperature for tank crews could be in excess of 60 degrees Celsius.
