Yeah, this very same jacket has been on Todocolecion since at least 2014. Because that's the dates on the photos I downloaded when I first saw it
It's definitely cut in the Spanish Army style, but the epaulets do not have the distinctive cross stitching at the shoulder seams and the chest pockets are not billowed. Those are two pretty consistent Spanish features. It also has velcro only for the front closure, which is also not standard (soldiers sometimes put it onto their personal jackets, but not from the factory).
I've always presumed it to be commercial, especially because the three features I mentioned are cost saving moves. Seeing as it has been available for 3+ years, I think it's safe to assume it is commercial.
That said, it's a very interesting use of the Spanish Woodland screens. Which, of course, means this isn't "Amoeba" as the seller calls it.
