I was just promoted to E-6 into a new unit (Transportation) that doesn't even have trucks yet. Any tips on how to keep my soldiers engaged?

Focus on basic skills as rifleman. If you've knocked out all annual training while waiting for your vehicles, I'd consider honing your "blocking and tackling" skills as a soldier. Land navigation, small unit tactics, formations and movement, reaction drills, combatives, etc. If you have anyone qualified to each urban skills or particular specialties, go for it. Get them spun up on FRAGOs. Is it their primary job? No. Will it help them on today's battlefield where the front lines are blurred? It could, and God knows your troops will love doing something out of the ordinary, like kicking doors or practicing to bash someone's face in with their rifle butt.

Began working on your platoon SOP. Get your initial counseling completed. Drill on convoy ops and crew serve weapon and engagement. And TCCC and Nine line. Land nav/BFT. That should keep you busy till your MTOE is up and running

Ssg Adair, I would start with going over the basics of a convoy with your soldiers. Using a blackboard or something like that. Go over basic information about doing a call for eod when there is an ied spotted.
