Soldier

-Aim at the ground when using the rocket launcher. Basicly aim at the person's feet. Look at it this way, If you miss the person and you were aiming horizontally, you don't hit them period. If you were aiming at their feet, they'd be hit a little from the splash damage.

-Also aim at their feet because if you get a clos hit, they'll go flying up in the air, and their landing will hurt them more!

-This is the second slowest class, so don't bite off more than yuo alone can chew and then retreat...they'll catch up.

-Defensive soldiers are really a necessity for today's base. They can take out any threat and guard just about anywhere from any nook or cranny (rocket jump).

-Speaking of the rocket jump...to execute one, aim straight at your feet and jump right before you fire a rocket. You will get hurt a little, but you will be able to jump over an obsticle, enemies, or get into the rafters in some levels.

-The super shotgun you have isn't so bad. If you are out of rockets, make sure to get more, but in the meantime use the super shotgun.

-This is the second most armored class too. In the respawn room, stock up on armor so it'll take more than one man to take you out.

-Also stock up on grenades in the RS room. One nail grenade can destroy a sentry. Two of the normals grenades can take one down, too. Bother grenades work well agaisnt all classes.
