True. Starting with 29 NATO members for standardization and interoperability among its' militaries IMHO. You'll recall the fall WSJ article "Russia Hacks NATO Soldiers' Smartphones". Check the list of what countries have troops on the frontier of democracy in Eastern Europe. We are not alone standing to face Russian aggression. The goldmine of intelligence the GRU (Russian Military Intelligence) is currently obtaining from these unprotected NATO member smartphones is tremendous! SFOR IP can help seal that mine entrance. DOD wants that multi-factor authentication as you wrote.
Newbies please read Ram's patent at the USPTO site."MFA/OOBA for mobile device" to come up to speed on this. Most importantly take note of the date. You will see he was first out of the MFA gate.
