My name is John Spencer. I'm the Chair of Urban Warfare Studies. I have studied & written about urban warfare for near 10 yrs. If I was defending a city, this is what I'd say/do. The manual is rough draft. It will be updated often. PDF download available https://t.co/nBVeczlKca pic.twitter.com/f9NXHxxs2k
