Grima Wormtongue is one of the two "rogues" of Isengard's heroes, and his specialty is in sabotaging the efforts of the enemy's rank and file as well as assassinating enemy heroes. At the start of the game, Grima is meant to be a spy who sneaks behind enemy lines and relays helpful information directly to you. Knowledge is important in warfare, as knowing what your enemies' tactics are can help you adjust your own tactics to counteract theirs. If Grima is spotted, he can escape easily, making him excellent at his job of spying without getting caught.
Later in the game, Grima becomes much less of a nuisance and far more of a disruption to the enemy's inner-workings. He will be able to weaken the enemy's armies and hero units--he will especially enjoy driving his knife into the backs of hero units, killing them instantly and denying the enemy's forces of leadership bonuses or juggernauts. At the peak of his power, Grima can completely shut down your opponent's buildings for a time, allowing you to take the lead in soldier production.
Being the snake that he is, Grima is vicious in the right situations with his poisonous words spitting from his vile fangs. But send a mongoose or a hawk after a snake, and you can bet your bottom dollar that a snake will never see the light of day again. Such is the lament of Grima Wormtongue. He is a bit slow when he runs, making him vulnerable to speedy cavalry or sharp-eyed archers. Also, while he is great at killing one enemy hero at a time, he can only backstab one at a time, so if two or three heroes are fighting him, he is powerless. His knife is also useless against monsters. With all of this in mind, make sure that you have your enemy distracted first by drawing most of their forces away and isolating their buildings or hero units for Grima to assassinate. When in doubt, order Grima to do a full-retreat back to the fortress if your back-up troops are unavailable.
Grima can be extremely dangerous for an enemy if properly used, orchestrating a push into the enemy castle by:
1) Killing their best hero 2) Reducing enemy armor and completely nullifying damage 3) Disabling the enemy castle.
