JL_Cmder wipes more closely to a traditional formatted hard drive.

The Options > Security Wipe does not wipe the device, just the personal data, preferences, email, calendar, etc., and may not even remove third party apps and their lingering data.

Use the JLCmder wipe and load a new OS fresh. I don't know how this compares to your DoD specs, but it is as close as you're going to get.
