The purpose of this manual is to provide information to enhance tactics and protection skills for those operating in high threat, protection and combat environments. This includes the operations of the following, by no means exclusive list: special operations forces (SOF), specialized military teams, security escort teams, high threat protection agents, tactical law enforcement and SWAT teams, paramilitary law enforcement teams, and also civilians intent on improving their tactical skills and knowledge. The information in this manual is derived from years of experience gained from training and operational service with SOF followed by years of employment as a security contractor in hostile environments including Iraq and Afghanistan. It is a distillation of military and security training, principles, and tactics, techniques and procedures (TTPs) adapted to the threat and environment anticipated in this type of scenario in order to provide knowledge needed to train tactical teams to operate effectively in high threat and combat environments.

There is an amount of material, the main bulk of the tactical stuff, which is common to both books. It is not intended that you buy both, just one or the other depending on your requirements.
