Marksmanship Tip of the Day

If you're on Facebook, drop over to "Marksmanship Tip of the Day". LCol Dave Grossman really got this one started for us when he asked Ori Pomerantz (who created "Sheepdog Tip of the Day") to parse our "Secrets of Mental Marksmanship" book for tips. Ori did a great job and the result can be viewed at www.facebook.com/marksmanshiptipoftheday.
