Most durable Astra Militarum unitsEvery Astra Militarum unit ranked by how much killing it takes in 40k 11th edition, counted in attacks to destroy it.

§ How durability is counted

Each unit is attacked alone, one attack at a time, until no model is left, 2,000 times over, by the engine behind List Check. A count is how many attacks that takes on average. Damage stays on a wounded model from one attack to the next, and what a model cannot take when it dies is lost, as on the table. Four weapons from the Space Marines datasheets do the attacking, with no rules of their own: the Intercessor Squad's Bolt Rifle (S4 AP-1 Damage 1, BS 3+), the Heavy Intercessor Squad's Heavy Bolter (S5 AP-1 Damage 2, BS 3+, Sustained Hits 1), the Devastator Squad's Lascannon (S12 AP-3 Damage D6+1, BS 4+) and the Bladeguard Veteran Squad's Master-crafted power weapon (S5 AP-2 Damage 2, WS 3+).

Intercessors is the one figure the boards rank by: how many Space Marine Intercessors (T4, W2, Sv 3+) take as much killing, taken over the four weapons as a geometric mean, so a count in the hundreds against bolt rifles does not drown a count of five against lascannons. Per 100 pts divides it by the unit's points; Intercessors themselves come to 5.9.

A unit defends with its own datasheet abilities, the wargear it carries and its army rule where that needs no situation: invulnerable saves, Feel No Pain, -1 to hit or to wound, -1 or halved Damage, Stealth. Detachment rules, enhancements, stratagems, attached leaders, cover from terrain and once-per-battle abilities are left out. TITANIC units, the Knights and Lords of War, are left off the boards as they open, since their size alone tops every one; the switch above the boards puts them back. Units come at the size and in the loadout the faction's winning tournament lists run most, from the Meta Merge feed of 2026-10-07; a unit no winning list fields comes at its smallest size in default wargear, marked †.
