I recommend “Fangs of the Lone Wolf: Chechen Tactics in the Russian-Chechen Wars 1994-2009” by Dodge Billingsley. He is a journalist who traveled a lot in country and later interviewed many combatants who had scattered around the world.
The book is not meant to be a general history, but is a nitty gritty, down in the weeds look at how the Chechens fought. The book contains 30 vignettes of various actions with detailed maps and diagrams and illuminating commentary.
The first war was fought by a bunch of Russians with drunks as leaders, Putin used carrot and stick and I assume the stick is impolite. The current president of Chechnya is a true Asiatic despotic character him and his golden gun and hot muslim chick pics are humorous.
So yeah if you are fighting Russian drunks bait their crappy armor into a city.
