Turkey - 890,700
Although Turkey has more soldiers than France, Italy, and the UK, it only comes in 10th in terms of military strength. France, Italy, and the UK are ranked 6th, 8th, and 9th respectively. Of course, all of these countries are part of NATO which means they combine to form the European branch of the world’s most fearsome military machine. So yes, if you wanted to rank the most powerful militaries in Europe it would be: France, then Italy, then the UK, and then Turkey.

It doesn't make sense. The number of soldiers doesn't mean much.
