I’m no expert. I’m not trained in Special Warfare. However, being a retired Undercover Narcotics Officer and being cross trained in USAR, Wilderness Survival & search and rescue, I found your writings, situational awareness &response highly plausible & well researched. The only thing that stuck out to me was having to use a knife to remove the take-down pins of he M4s taken from the dead goons. I have never used anything but my thumb and fingernails, but I am not 100% knowledgeable on the newest models. Starting book two now. Thanks for the great read
