Unturned raid calculator

Pick a wall, door, floor or any other placeable to see how many charges, rockets, grenades, bullets or melee hits break it. Worked out from the game files of Unturned 3.26.3.14, for a default server unless you change the settings below.

How it's worked out

An explosion hurts every structure and barricade inside its blast radius that it can see, so one charge can damage several at once. Its damage falls off in a straight line from full at the centre to nothing at the edge. The calculator assumes the explosive is touching the target: grenades and rockets go off on its surface, and a placed charge sits 5 cm off it, which costs the Demolition Charge 0.6% and the Precision Charge 1.7% of their damage. A rocket that lands a metre away does noticeably less.
High-tier placeables take half damage from everything: metal and brick structures, metal barricades, and the few others the game marks high tier (jail door, vault door, bars fortification, locker, tanktrap, large slippery plate). Wood and everything else take full damage.
Bullets and melee only hurt placeables the game marks as vulnerable (plates, bedrolls, spikes, crops and the like), unless the weapon is a heavy weapon (Timberwolf, Dragonfang, Grizzly, Shadowstalker, Matamorez, Ekho, Shadowstalker Mk. II). Explosive rounds (rail rounds, HMG boxes, explosive arrows) burst a quarter of a metre out from what they hit.
Each hit is rounded down to a whole number before it comes off the target's health. Shotgun shots count every pellet hitting. Weapons at 50% quality or more do full damage; below that, less. The Overkill skill adds up to 50% to melee, which isn't counted here.
The Sticky Grenade was called C4 when it was added, and many players still call it that. "Charges" are the Demolition and Precision Charges you set off with a detonator.

Server plugins can change raid damage too. Read from the game's own damage code and item files; nothing here is measured in game.
