I'm just wondering what experience your vets have in the end-game? I am always struggling to have more than 2 chevrons still in 1799. Most of my initial troops have that, but not more. Rarely would somebody be with 3 chevrons.

For ships it's even worse. Playing as Britain, in 1799, my highest veterancy ship was a 4th rate that had 4 chevrons. But that 4th rate I captured from the French AI at the start of the game and it already had 4 chevrons then.

So, is anyone else able to achieve higher troop experience? How do you do that?
Would campaign difficulty have anything to do with how fast experience is gained?
