Bulk orders are not unusual.

Military literature has focused on insurgency/counterinsurgency for quite some time.

The cultural focus, post 9-11, has steadily been revolving around patriotism and "terrorists".

Just the word "terrorist", is a trigger-word; it has become a propagandized term for insurgent.

Previously the words have had different meanings in a technical, military, setting; their use was not interchangeable.

This dilution and intentional obfuscation of language is revealing, in and of itself.

It is hard to consider a public bid secret; to call it esoteric would be a stretch.

But your curiosity is refreshing.

Good find
