The scientific method is a method to create and verify plausible explanations for phenomena.
Strategic thinking is a method to make decisions in face of uncertainty. There is nothing scientific about it, though there are tactics in which a commander might make probing attacks to gain intelligence and test the adversary. Ultimately though, you are making decisions and taking action with inherently incomplete information.
One of the things that happen in adversarial dynamics is to use misinformation to screw around with someone else's OODA loop.
So no, OODA and strategic thinking in general are not essentially just another name for the scientific method, though it may employ science, or a skeptical stance as one of many tools to make decisions and take action. That frame of thinking exposes a limited understanding of OODA and strategy, one that is exploitable by an adversary.
