Most Successful Military Nation Ever?! :DD?

Well I am a U.S Army soldier. You cant really say the U.S because we are centuries younger than other countries. I would have to say the Britts were the most successful. The U.K basically dominated the world at one point. They found America, had control of most of Africa, and India. AlsoI have respect for Britts for there fight in both world wars. Before America got involved they were the only oness who could stand their ground, I meanno offense to the French..but come on U.K you have to know what im getting at. Also as an American soldier I hold the U.K in high reguard because of the help they give us in Iraq and Afghanistan. The only ones who Really have the and honor the NATO alliance, and have contributed thousands of troups instead of a hundred like some other NATO members.
