How to defeat a striking enemy in Halo 3 Movie

Game for Xbox 360Halo 3I tried collecting movies of how to defeat the enemies that I can not imitate easily. The sniper from a distance is not so easy, but the technique of this movie seems to require not only technology but also luck.

The playback of the movie is from the following.
First of all, a famous movie. Placed far away from the plasma grenade, it fell directly above the air outlet and was blown up as it was, adhering to the player's arm nearby. It is not something you can easily target.

Placed with the Energy Sword, you can throw a plasma grenade from behind. The grenade rebounds against the bubble shield just in front of you (it blocks the attack from the outside) and sticks to the body and is knocked down. What a bad luck ....

Because all of the terrain-enabled vehicle mongoose has no armament, it will only be a means of travel unless you put someone on the rear seat, but you can also kill if the enemy is walking. In this movie, I'm killing in jumping.

The end is hitting a mongoose. I did not think there was any such attack method.

The way to make a vehicle big jump succeed by myself is explained in the following movie. Since specification changed with Halo 2, two plasma grenades are necessary.
