The "evidence" presented that this was a military camp appears to have consisted of there being some guns (in a country where guns are as common as in the USA), some money (about $800 or so), some passports (at a wedding where family members from both sudes of the border with Syria a few miles away would be present) and a satellite mobile phone (in a part of the world where that's the only kind of phone that works). And the suggestion that the idea of a wedding being held in a small village away from a town is highly suspicious.

In other words, nothing at all.
