@TheDarkKnightWhy I write:
While I do wish to keep my brain engaged; that is not the primary reason I write.
When I was in 5th grade I started Reading about people's experiences in combat. I dreamed of becoming a Fighter Pilot! Multiple reasons that I never achieved that goal. Instead, I became a Paratrooper jumping out of aircraft, rather than flying them...
I have been a voracious reader since age 4. In the US Army I continued to read. In particular I used the USMC Reading Program(s) as a guide.
What I learned in books added to what I had been Trained. (Mostly by Veterans of the war in Vietnam.) Knowledge I gained saved my life, and the lives of fellow soldiers.
As a veteran NCO I passed on as much knowledge as I could to other soldiers (and members of other services).
Most people don't understand what combat of any era is like; let alone modern combat. Less than 3% of citizens in the USA have served in the armed forces. Less than 1% of those who served have been in a Firefight! (Engagement using small arms [rifles, carbines, machine-guns, etc.]). I've "Been There, Done That, Got the CIB!" (Combat Infantryman's Badge)
I hope that I can inform people, at least a tiny bit, about what war in the 21st century is like. Hopefully, I entertain them too. I realize that by depicting Logistics, and other boring matters, I likely don't have much of an audience...
Mostly, I Write for Me! Stories that are bursting to get out! Unfortunately, technical matters, and difficulties getting my writing proofread, let alone edited, delays getting my writing posted...
When I have "Writers Block" (or other issues) with one WiP (work in progress), I work on another...
Anyway, that is Why I Write!
