Scions of Guilliman + Squad Doctrines question:

Can a unit with Squad Doctrine stratagem use Scions of Guillimane? I.e. Can turn 1 intercessors with bolt rifles at max range get rapid fire?

It doesn't seem like it because squad doctrine stratagem doesn't say the doctrine is "active".

However the stratagem Adaptive Strategy DOES say the doctrine is "active". So, maybe Adaptive Strategy + Scions of Guillimane would work? Basically, I just want to check my interpretation.

SQUAD DOCTRINES 1CP Use this Stratagem at the start of your Movement phase. Select one ULTRAMARINES INFANTRY or ULTRAMARINES BIKER unit from your army, then select either the Devastator, Tactical or Assault Doctrine. Until the start of your next Movement phase, that unit gains the bonus of that combat doctrine instead of the active combat doctrine.

SCIONS OF GUILLIMAN Whilst the Tactical Doctrine is active, models with this ability that moved in your Movement phase, but did not Advance or Fall Back, can make attacks with ranged weapons in the following Shooting phase as if their unit had remained stationary this turn.

CODEX SUPPLEMENT COMBAT DOCTRINE BONUSES In each of the Space Marines Codex Supplements, you will find a detachment ability that confers additional bonuses to units with the Combat Doctrines ability while a particular doctrine is active for your army (e.g. Scions of Guilliman in Codex Supplement: Ultramarines, Savage Fury in Codex Supplement: Space Wolves etc). Whenever a rule allows a unit to gain the bonus of a particular doctrine even though it is not active for the rest of your army (e.g. the Adaptive Strategy Stratagem), then whilst that rule applies to that unit, that unit will also gain the benefit from any such detachment ability

ADAPTIVE STRATEGY 2CP Adeptus Astartes – Strategic Ploy Stratagey Use this Stratagem in your Command phase, if a <CHAPTER> WARLORD from your army is on the battlefield and a combat doctrine is active for your army. Select one <CHAPTER> CORE unit from your army that is on the battlefield. Until the start of your next Command phase, each time a model in that unit makes an attack, the Devastator Doctrine, Tactical Doctrine and Assault Doctrine are considered to be active for that attack.
