Why doesn't the Army spend more money on effective communication for Soldiers, especially leaders?

Many Leaders in especially high OPTEMPO units simply want the job done.
Screw up = reprimand and blamed
Wasn't your fault? Oh well.
Ask too many questions = PIA that's seemingly incompetent

Just what I've seen.

That's a great question, 1SG (Join to see). I have attended some great communication seminars and classes. Some were paid for by the Army, some by DoD, some by me. I think all Soldiers, NCOs, and Officers could benefit from more and better effective communication training. It's a critical skill in the military and just about everywhere else.
