High Intensity Military Urban Combat
The book High Intensity Military Urban Combat focuses on exactly what the title says. It aims to teach in the very relevant task of high intensity war in built-up areas. To an extent (being adopted from an official use only instruction) it’s focused on a military audience and having them “unlearn” the circumstances of low-intensity urban war (superior resources, ability to do complex operations, rightful focus on collateral damage) compared to a slugfest in Seoul/Tallin/Taipei (or wherever. There are a lot of big cities!)
Focused on squad level operations, it’s well-illustrated and detailed. To a degree, it duplicates what’s in existing publications, although trading field manual-ese for clear text and good diagrams is a welcome tradeoff. I can’t say how helpful it’d be to a professional audience, but to an armchair observer like me it’s illuminating.
