Warfighter Modern: Canada 2! (Expansion 31)

The Canada#2 expansion gives you more Player Soldiers, Non-Player Soldiers, and Squad Soldiers from Canada. Also included are their Weapon and Equipment cards.

This provides you with everything you need to run missions.
All you need to do is use these Soldier, Weapon, and Equipment cards instead of the US cards at the start of a Mission, and you are good to go.
