Romania
Romania is ranked at the 41st position of most powerful military forces. Though they spend quite a bit on artillery and mine warfare, this is still not a nation defined by its military involvement. They have 70,000 actives and 50,000 reserves to help protect them if need be.
Bangladesh
There are 204,000 people active in the Bangladesh military right now, but there are exactly zero reserves. Highly ranked in terms of its parliamentary forces, manpower, frigates, and more, this is certainly a fascinating exploration of military involvement. Bangladesh is a surprising force!
