[Lord of the Rings] Do the Uruk-Hai inherently know how to fight skillfully?

In the Two Towers, the Uruk Hai bred to attack Helm's Deep know battle formations, can wield crossbows, use siege engines, and are able to duel trained elves to the point where they can pretty much slaughter them.

Were they taught how to do all that, or do they have some sort of inherent knowledge about how to fight as soon as they're born? It doesn't look like they'd get much training or instruction in, given the amount of time they had before they were expected to take over Rohan.

Sounds like "Movie Version".  IIRC, there are a couple really short scenes in the movies that show them doing some form of practice against each other... usually in the scenes showing them being bred.
