We can't keep deploying a limited number of the same troops up to 4-5 times per enlistment into combat for a year at a time and not expect major cognitive issues. We need a military with a one deployment per enlistment policy into combat with a 18 month limit.
We can do that but congress has held the End Troop Strength numbers at 1996 manpower levels in the active forces since 1996. You can't run a machine without needed downtime nor can you a human being.
Excellant summary.
Fortunately we now have very effective treatments for PTSD,
We have Brain scans, SPECT analysis ( Dr Amen) ...EEG therapies ( similar to biofeedback); good medications when used appropriately, and many new cognitive behavioral and EMDR therapies; new medications and therapies for substance abuse. Vets are getting better, and sooner in their lives. This not only helps them, but their families, especially their children...who now have a healtheir parent.
