Rangers

In my opinion rangers are best for scaling the walls of forts, hiding in tree patches, and getting right in the enemy's face!!!

Grenaders

Grenaders are best for ambushes, defending, or assaults on forts.

Grenaders are best for what they are named for... GRENADING!!!

Grenaders are best at staying on top of the front wall of a fort when defending to drop grenades on enemies from above.
