Satchel Charge

The Satchel Charge is a Call of Duty: World at War perk used as a remote detonated bomb. Much like C4 in Call of Duty 4: Modern Warfare. It can also be found in Call of Duty: United Offensive's multiplayer

Call of Duty: United Offensive
The Satchel can be used to set traps near where an enemy is. Throw one near an important location, such as in a sniper nest, in front of an important doorway, or under a vehicle. They're also hard to spot, so feel free to toss them in corners enemies have to get near. Just remember that you can only hold one at a time.

Call of Duty: World at War
Satchel charges are the C4 of World at War. It is primarily used to lay out traps, and is used destroy tanks. Players use this in search and destroy to booby trap the charge placement area, so when the bomb is activated a player can set off their stachel to kill the person who placed the bomb. Also note that when a tank drives over a satchel when it is set off, the tank will be destroyed instantly. If you can't place one under the tank it only takes 2 satchel charges in the back with Fireworks as one of your Perks. Experienced players can also be seen using it to snuff out any Bouncing Betties diminishing the need to cook frag grenades.
