Warhammer 40k’s Adeptus Astartes Excel At Specializations

What Are the Adeptus Astartes in Warhammer 40k? Humanity’s Genetically-Engineered Guardians

In essence, the Adeptus Astartes are warrior-monks: they’ve traded personal lives and normal human experiences for a singular purpose—defending humanity at any cost and becoming a Space Marine. Their power armor makes them walking tanks, and their bolters (basically rocket-firing guns) are designed to annihilate anything that looks at them funny. These guys aren’t just fighters; they’re living legends designed to inspire hope among allies and terror among enemies.

Rules and Gameplay Mechanics for Space Marines in Warhammer 40k 10th Edition

Oath of Moment

Combat Doctrines
Space Marines utilize Combat Doctrines to adapt their tactics during battle:
- Devastator Doctrine: Focuses on heavy weapons, granting them the [HEAVY] ability. If a weapon already has this ability, attacks made with it add 1 to the wound roll when the unit remains stationary.
- Tactical Doctrine: Enhances rapid movement and assault capabilities. Ranged weapons gain the [ASSAULT] ability, and attacks targeting units within 12″ add 1 to the Strength characteristic.
- Assault Doctrine: Optimizes close-quarters combat, though specific benefits are detailed in the full rules.
These doctrines allow for strategic shifts, enabling your army to respond effectively to evolving battlefield conditions.

Datasheets and Unit Abilities
