Wolfenstein: Enemy Territory/Ranking

Experience
Experience points are earned when the player accomplishes certain tasks. There are three areas in which players gain experience, and eventually level up:
 * Battle Sense
 * Light Weapons
 * A third, class-specific area

Each is covered in greater detail below.

Battle Sense
Battle Sense is a bravery skill that rewards all classes for surviving combat. 2XP is gained per 30 seconds while inflicting damage. 5XP is gained for every 30 seconds while inflicting and receiving damage. 8XP per 30 seconds is gained while killing an enemy and receiving damage. Rewards for levelling up in battle sense are:
 * Issued Binoculars: Press B to activate your binoculars. Field ops can use binoculars to call artillery strikes and covert ops can use binocs to spot landmines.
 * Increased Physical Fitness: The powerful aerobic benefits of prolonged combat activity enable your Stamina bar to recharge at 160% of the normal rate.
 * Improved Health: Increases your maximum HP by 30 points.
 * Trap Awareness: Even if you're not a Covert Ops, you'll be able to sense enemy Land Mines without the aid of Binoculars. Any mines within a certain range will appear as translucent outlines in your field of vision. Unless you're a Covert Ops, you won't be able to spot them for your team-mates.
