I've put together a comprehensive playlist from S2 Underground https://www.youtube.com/@S2Underground and a few other resources going over intelligence preparation. The videos are in order from highest to lowest priority for an individual spanning to strategic level operative contingency with an entire team. https://www.youtube.com/watch?v=850LCN0KcNM&list=PL43q_4FGB4dqECvUJI-_LlyKdYxtmOXnc&index=1
