Bouncing Betty

A Bouncing Betty is a World War II-era mine featured in Call of Duty: World at War. It is unlocked at level 24 on online play. It is also a perk that replaces the Claymore x2 from Call of Duty 4: Modern Warfare. They are significantly better than claymores for a number of reasons. They explode 360 degrees and are much easier to conceal because they are smaller and have no red lasers. They are also "dug in" thus, you will only see a dim glowing yellow rod sticking out which usually never catches the eye of the player. Also, if a player walks around with the pin pulled, they will drop it to the ground when they die, which can be used similarly to Martyrdom. Much like Call of Duty 4 claymores, Bouncing Betties, once placed, remain until exploded or the player who sets them respawns after dying. Bouncing Bettys are not in the campaign.

Note that in Call of Duty 4, there were red lines indicating where the claymore would explode. There are no such lines, since the Betty mine explodes 360 degrees.

Suicidal Soldier
To do this trick, have Bouncing Betty's, a pistol, and the camouflauge perk on. First, put one Bouncing Betty on the floor of a very big place where fighting occurs often. Next, go prone on the Bouncing Betty and aim a pistol downwards. Now, just wait until someone comes by you and activates the mine. You will die, but it counts as a suicide so the enemy doesn't get points but you do. If no one comes, move and repeat the process.

Other Tactics
Often praised for their higher camouflage ability than claymores, these mines are primarily used by snipers, but players who are not snipers use them in high trafficked areas or choke points. They can be particularly useful in area denial, specifically to prevent flanking or to protect an objective. In Search and Destroy they remain even after the player who set them has died, making them very useful for defending a bomb site before (defense) or after (offense) the bomb is planted. A good strategy to use while fielding this weapon is to put it just inside the door on right or left, this way they can not see it even if they are looking for them.

Trivia

 * "Bouncing Betty" was not the real name given to the device. Its real name was the S-mine (Schrapnellmine in German)
 * Realistically, one could not place a "Bouncing Betty" wherever they wanted. They could only be placed in soft ground.
 * Bouncing Betties were pressure-activated. This makes them unrealistic in Call of Duty: World at War because they are activated simply when an enemy walks near to one.
