This is an Audio PMCS App for Army, Air Force and Marine Corps HMMWV's. It has weekly, monthly, before, during and after PMCS. It also provides the correct item numbers you will need to appropriately fill out the PMCS forms correctly. All you have to do is hit a button and listen for all the checks you have to do. If you find a Deadline, or Non Fully Mission capable, you would fill out your form using that actual item number so the mechanics do not kick it back or ignore it because you just listed a component problem. Seems like they love it when you check Non Mission Capable but do not put the correct item number from the manual on the form. It was produced by ArmyADP.com now the New Army Study Guide. It has the most current, up to date and accurate promotion and competition board questions and answers to prepare you for your promotion to NCO. This app itself was developed for Soldiers at all levels to perform PMCS on the Military's most common and largest vehicle inventory in all branches of the service to include the Nation Guard and Reserves.
