Marko would arrive at the base have his ID scanned at the post and motor his car through the gate and into the parking lot.  He would make his way with his duffel bag around his shoulder to the entrance and get scanned through.  He would have his retinal ID checked as well as the barcode on the back of his neck.  IT would identify whom he was.  He would take and make his way into the briefing room after dropping off his equipment at the weapons locker.
