20) Canada

Budget: $15.7 billion

Active Frontline Personnel: 92,000

Tanks: 181

Total aircraft: 420

Submarines: 4

Canada kicks off the list due to the country's small number of active personnel, its limited supply of aircraft carriers and attack helicopters, and its lack of tanks and submarines. However, Canada has still taken part in US operations in Afghanistan and Iraq, and it is also a member of the NATO military alliance.
