The bottom line is that there is no direct progression from DEO to Deputy. Federal service is always beneficial, but nothing special coming from being a DEO. I know a few DEOs that have made the leap to Deputy. I also knwo a few that are rotting it out as a DEO. If you would not get the DUSM job without being a DEO, you likely won't get it as a DEO (if that makes sense).
