Tactics is that portion of decision-making applied to repetitive patterns and recurring situations. Strategy is that portion of decision-making applied to situations that are unique or unlikely to reoccur. Procedures are tactical. Decisions are strategic. In a chess match, the opening book is tactics, the mid-game following the combinatorial explosion of potential moves is strategy, and then the end-game is back to tactics, after the board has been reduced to fewer pieces. In the real world, breaching and clearing a modern urban building is tactics. Part of the squad covers as the remainder moves. Corners are checked before moving around them. Doors are checked before opening. There is still a strategic element, in that any given building will have a unique floor plan, but with sufficiently developed tactics, the strategy portion becomes somewhat unimportant. Capturing and occupying a specific city is strategic. The tactic of breaching and clearing buildings will be used many times in that strategy, and so too will the tactic of erecting concrete T-wall barriers and creating checkpoints, but the choices of where to start, and in what order to proceed, are all strategic. It is difficult to separate the terms, because every real-life situation will have some portion that can be matched to a general pattern, and some portion that represents the variance from that pattern.
