Rust Monument Blockers

1 C4 clears any blocker. Cheapest to craft: 4 F1 Grenades (240 sulfur) for the Barrels, Barrels Long and Trolley; 70 Explosive 5.56 Rifle Ammo (1,750 sulfur) for the Barricades, Blast Door, Desks, Lockers and Terminals; 71 Explosive 5.56 Rifle Ammo (1,800 sulfur) for the Collapse; 5 Explosive 5.56 Rifle Ammo (150 sulfur) for the Vent Cage. Mine one with a Pickaxe instead to get its metal.

The count of one explosive that clears a blocker at full HP, cheapest sulfur first. The number under each is the sulfur to craft that many. 40mm HE grenades come only from loot, so they have no sulfur cost and sit last. Rockets, grenades and 40mm do not hurt the Vent Cage: stick a C4 or a satchel on it, or shoot it with explosive ammo. Explosives give nothing, so mine a blocker when you want what it holds. The Raid Planner adds up boom for several targets.

Methodology

Explosives tested in game: we set off each explosive on every blocker on our own server and read the HP it took. C4 and satchels were stuck to the blocker, rockets fired at it, explosive ammo shot into it.

Places tested in game: we started our own server on several maps and noted every blocker, the door it stands in front of and the crates beside it.
