Call of Duty 4: Modern Warfare/Boot Camp

Boot Camp is the first set of challenges you unlock. You will get them after rank 9, these challenges will give you points for doing certain things (most of these are easy.) This table will show you all of them, the XP points earned and tactics to get them. {| !Challenge !Rank Unlocked !Requirements !XP !Tactics

 * Marathon
 * 12
 * Sprint for 26 Miles
 * 250
 * This challenge will probably take the longest time to do, so don't attempt to do it in one go, but instead of walking, run, this is a good tactic anyway so try and use it and it will help get you closer to the 250 XP.
 * Goodbye
 * 12
 * Fall 30 feet to your death
 * 250
 * There is a building near the Crashed plane on the map crash, it is four stories high and jumping off it will give you the experience, also in District look for the well between both sets of stone steps and jump in. The map Countdown has several missle silos, jump into one of those will give you the challenge.
 * Base Jump
 * 12
 * Fall 15 feet or more and survive
 * 250
 * Jumping off the top of most buildings or high ledges will give you this as long as you are on or near full health
 * Crouch Shot I
 * 12
 * Kill 5 enemies while crouching
 * 50
 * You should crouch behind cover when you are looking for people to kill or need to recover health, if you kill some people while like this then you will earn the XP.
 * Crouch Shot II

 * Kill 15 enemies while crouching
 * 100
 * Crouch Shot III
 * 12
 * Kill 30 enemies while crouching
 * 250
 * Prone Shot I
 * 15
 * Kill 5 enemies while being prone

 * 100

 * Kill an enemy with a grenade
 * 50
 * You could use the martyrdom perk to do this or you could throw a grenade into every building you see, as you get another one when you respawn, it is not really a waste, you could also wait until you see an enemy or a group, cook it and throw it. The Sonic Boom perk might also help.

 * 50
 * An assist is where you damage an enemy but do not kill them and a team-mate kills them, you will get an assist, they give you 1/5th of the score of a kill usually, it is usually a good idea to throw a grenade or use a rocket launcher in an enemy area in a team game (all except free for all) and you will get some kills and maybe a few assists. You may also just aim to shoot them a few times and not kill them but this is quite dangerous.
