What are Doctrine paths?

Each faction has two Doctrine paths, featuring a different set of units that benefit from different faction bonuses:

Space Marines:

• Tactical: Units deal more damage against Infantry targets and have increased bonuses on Dense, Rugged and Urban terrain.

• Devastator: Units have more hitpoints and deal more damage against Machine targets.

Astra Militarum:

• Born Soldiers: Units are deployed in less time and for lower costs.

• Armoured Soldiers: Units have more hitpoints and deal more retaliation damage.

Orks:

• Speed Waaagh: Units move faster and have increased bonuses on Open, Elevated or Difficult terrain.

• Big Waaagh: Units have lower upkeep costs and gain bonus damage when stacked with many other units of the same type.

Chaos Space Marines:

• Pactbound: Units are harder to kill off, retain more combat power when low on hitpoints and deal more damage to buildings and zone morale.

• Malefic Host: Units deal more attack damage against units and move faster in enemy territory.

When you level up the units in a path, their main stats as well as their faction bonuses increase.
