I've been reading about Chapman's CQB for LE and Armed Civilians for a number of years now. I sure wish I'd have had to opportunity to take his classes back when I was healthy and whole.
Disabilities come with age, and I've come to find my Grandfather was correct when he told me many years ago, "Growin' Old Ain't For Sissies!"
I had the opportunity to take one of Chappy's courses over at Alliance, Oh approx 2 yrs ago. That was when I too was "healthy and whole" and in good shape. If you ever get the chance to take one of Forge Tactical courses "just do it". Now that I'm recovering from my fifth back surgery hopefully in about six months I'll be able to shoot, move and communicate once again.
