Satchel Charge

You should throw a satchel charge from safe distance (about 2 foundations in my opinion) from door/wall that you want to destroy, because if you throw it standing near the structure, it may or may not explode instantly in your face and kill you, because splash damage of satchel charge is lethal to players, if you stand very close.

The explosion will draw attention of other people and gets you a chance to get their gear.

Good for early and mid game raiding since you only need a Work Bench Level 1 . Much cheaper than a Timed Explosive Charge but not as fast so not as good for end game raiding. Also you need to know how to make a Beancan Grenade before you can make it.

Satchel charges are a great raiding tool, sometimes they will result in a dud but can be re-ignited to explode. They are quite useful and powerful depending on how much time you're willing to spend on farming for sulfur, getting wood, or even looking for rope.

Satchel Charges will make a significantly higher pitched sizzle prior to either dudding or exploding.

Satchels (and TECs/C4) deal splash damage to entities (placeable items, players etc) but not to permanent structures built with construction blueprints (i.e. they only damage the specific structural piece they're attached to). Be careful not to miss the exact section of wall/door or the explosive will be wasted. Rockets deal structure splash.
Due to the random fuse, the ideal way to use satchels is to throw the exact amount you need from just outside the blast radius, all at once. Practice the throwing arc in a modded server. Duds will never be lost/wasted while the structure they're attached to is still intact, nor will they be destroyed or detonated by other satchel explosions.
