Why? DvLs aren't typically out patrolling and sweeping. Now they may be outside the Nexus and just talking to the citizens, but that's it. They're not meant to be field commanders like an OfC is. That's like sending your General to go out into the battlefield and possibly get blown up by some Jihad or something. This isn't BC times where you had your General lead you into battle to show his dominance. This is modern times where they keep their heads quite protected and not out and about doing the job of ground units. Just let them flaunt their uniform and show their achievements. As I stated before, the OfCs are the field commanders, not DvLs.
