How Nations Stack Up

Some nations bulk up their armies like they're bracing for a storm (and perhaps they are). While others keep things lean and allocate almost no resources toward bolstering their military strength. There's a wide spectrum of military power out there. That's what makes comparing the world's largest and smallest armies more interesting than you might expect. First up—let’s take a look at the biggest forces on the planet.

Some nations get by with forces so small they're almost invisible on the global stage. Let's meet the countries proving that size isn't always the strategy.

1. Vatican City

Vatican City holds the unique distinction of hosting the smallest standing force in the world, the Swiss Guard. Comprising fewer than 150 soldiers, these guards serve more than ceremonial roles. They also provide real, trained protection for the Pope within the tiny sovereign city-state.

3. Tuvalu

With a population barely touching 11,000, Tuvalu's security approach remains minimalist. It has no standing army, relying instead on international agreements and neighborly goodwill.
