ASV Team Needs Your Help

The Armored Security Vehicle sustainment team needs your help. They’re checking on what MWOs have been applied to each M1117 armored security vehicle (ASV) so the Modification Management Information System (MMIS) database can be brought up to date.

The ASV team asks that you physically check for each MWO application, not just the MWO tag, and update the MMIS database. You’ll find MMIS on the LOGSA LIW website:

Here is a list of all ASV MWOs, along with artwork showing each application for quick recognition. Questions? Contact TACOM’s Kevin Fritz at DSN 786-8873, (586) 282-8873 or by email:
