Your books are truly eye openers. Thanks for your work in the preparedness field.
Regarding your recommendation of getting OC with at least a 12% concentration, as an OC instructor, I recommend that buyers ask: “12% of what?” A 12% concentration of a 250,000 Scoville Heat Unit (SHU) spray may prove ineffective. The true test of an OC spray is the SHU rating. I recommend a minimum 2,000,000 SHUs. The concentration only affects recovery time.
The 5% is great for training. You should recover in 15-20 minutes. Anything over 10% is great for application to the faces of bad guys. It takes as long as 45 minutes to recover. Just my two cents. Thanks again for the lessons that SurvivalBlog provides. – Brian M.
