The Defence of Duffer's Drift is an early example of this genre.

In the first story in the book you learn how to do platoon level tactics badly( and lose most of your men )

In each subsequent story, a few tactical parameters are tweaked and the story is recounted again, with improved results.

The same approach is used in newer tactical books like Musicians of Mars 2.

The first Team Badger story in Musicians is very similar to the first story in Duffer's Drift, allowing for changes in location, equipment and techniques..

"The lingering sulfur odor of gunpowder, mixed in the haze of the dust and smoke of battle, dominated the senses of CPT Fred Morris, commander of Team Badger. He sat amid the wreckage of what used to be some of the world’s finest combat machines, M1A2 Abrams tanks and M2A3 Bradley fighting vehicles.

Now most of his company’s tanks and Brads were mere smoking hulks, emanating the distinct smell of burning electronics to add another element to the senses of the dismal scene before him.

He sat, quietly reflecting on the sequence of events that led to the destruction of his beloved team. His mind raced as he recounted how the enemy force, so much more formidable than he had expected, employed assets, capabilities, and tactics that he had not taken into account. At the same time, he wondered why he was unable to bring to bear his own extensive combat power to earn decisive victory. He had felt so ready, so confident, and believed that his team had prepared so diligently.

Yet, still they had been defeated so soundly. How could that be? LTC Joe Milner, the task force commander, had given Team Badger the task to defend the center of the task force main battle area (MBA) in an area defense to destroy the attacking enemy motorized rifle brigade. Specifically, CPT Morris and Team Badger were to defend against the enemy’s main effort motorized rifle battalion in Battle Position (BP) Badger, along the enemy’s most likely avenue of approach.

That motorized rifle battalion plowed through Team Badger as if it were not even there."
