A common complaint levied at games like Panzer Corps and Unity of Command is that, really, they fit more within the realm of a 'tactical puzzle'. Your mileage will vary on the truth of this, but what can be stated is that games that follow this model like to offer a set-piece or a specific challenge. Your job is then to find the optimum way out of the predicament put in front of you.
The argument is that this differs from 'real' tactical games where there is a more loosely defined objective, and you simply have to use the tools you are given to achieve it. I suspect this kind of distinction really comes down to how easy a developer finds it to code a challenging AI.
We were very excited when we learned of the impending release of Möbius Front '83. On the surface, it looked like a tactical hex wargame set in the Cold War. The developer, Zachtronics, are known for their creativity in playing around with different genres and how they intersect with puzzles, but this gave all the appearance of being something new entirely.
