Paul G. Markel has released Airsoft and Airguns for Tactical Training, a workbook aimed at people whose ranges bar tactical drills. He outlines how airsoft and airguns, especially full-size gas replicas, let shooters rehearse tactics from earlier instruction and build skill when live fire is unavailable.

Markel treats live fire and dry fire as essential and does not present airsoft or airguns as a substitute for dedicated live-fire work. The book offers concise suggestions for making practice time more productive and is sold now on Amazon in paperback and Kindle editions.
