Morning SDML !
In my opinion and 6 back-to-back tours with DIA in various capacities, I would say join. I am one of those who had raised issues about DIA personnel morale. Those issues however had more to do with relations between the Department of the Army and DIA, leaving Army personnel in limbo.

Are you mature enough to not be entangled in the snare of faint and negative environments and still get your job done to the best of your ability? Or, do you need an outside structure to allow your success?
Greetings Sam !
Very clear-cut and well put. I had few dealings with the D.C. end so most of the negative conditions surrounding us were not distracting, rather merely frustrating. DIA field work has its professional rewards and once in the field, social and cultural conditions establish "environments", positive and negative.

Regards, Stan
