You made a claim about historical events, you back it up.
I CAN back up that offence policy results in materiel and deployment (because those are the actions it can take) and defense results in defensive infrastructure in core territories (because those are the actions it can take.)
Your claim that it directs tactics (which generally aren't even under the purview of the king unless he's on the battlefield) is narratively unlikely. OTOH, since you claimed it's happened in the past to us, you presumably have some evidence...

I believe you, hence the request for citation.
