The Royal Vanguard are elite scout cavalry units of Rohan which cost no command points but are limited to three battalions. In addition to that they take to the field very quickly (almost no recruitment time) and can move into a wedge formation. They are upgraded versions of Exiles, and they can be recruited from the upgraded version of the Exile Camp, the King's Camp (cost: 1000).
The Royal Vanguards can be given the following upgrades:
- Other infantry if they are swordsmen
- Monsters and Cavalry if they are pikemen
- Buildings if they are cavalry
It is important to note that while you are limited to 3 battalions of Royal Vanguards, you can also train your 3 battalions of Exiles from the Exile Camp before you upgrade it to the King's Camp. Aside from costing 0 command points (unlike the Exiles) and having a quick training time, the Royal Vanguard are not much different from your regular Rohirrim. Therefore, to maximize their particular benefits, the strategy with them should be to use them to set up an ambush or rush them to defend the outpost/nearby settlements/heroes. Recruitment speed is the main bonus.
