Whenever some entity claims an association with the military, you always need to read the statement closely. Note that the military tests a lot of things and consequently rejects most of them.
Just because it was "tested" or "developed" by the military doesn't mean it was found useful or subsequently was adopted for some use. Testing is just that, to determine efficacy. I can "test" water in my engine as a substitute for oil.
Here is the statement on their website, read it closely. It actually says nothing

Working in conjunction with the military and with Boeing Phantom Works, NanoProMT is engineering product specifically designed to meet strict requirements and rigorous demands of cutting-edge institutions. And we’ve been put to test, undergoing extensive lab- and field-testing that has led to military-grade formulas being applied to all NanoProMT products.
In fact, looking at the way it is a carefully crafted and worded statement makes me believe it is intended to obfuscate not inform.
