Global hours means hours overall. Other awards will spec out hours as a certain nationality.

The big difference in the Expert vs Veteran vs Basic is the hours. You cant be called an expert or veteran with only 12-24 kills in a round. Hours will prove ones skill or at least I think thats the strategy behind the levels.

If you think the Veteran badges are extreme, check out the Expert ones as far as hours.
