ISIS last year moved its research labs, experts and materials from Iraq to "secured locations" inside Syria, apparently out of concern of an eventual assault on Mosul, Iraq's second largest city, which it occupies.

Ollivant said that the details in the video are sure to ratchet up the concerns of veteran military and intelligence officials who have watched the rise of ISIS with alarm — especially its attempts to transition from a stateless terrorist organization to one with the advantages of a nation-state.

Ollivant said that U.S. intelligence and military agencies will be combing through the video to authenticate it, and also to glean possible details of new ISIS capabilities — and locations that they can target with military action.

"I'm sure the agency [CIA] is all over this and I'm sure JSOC [Joint Special Operations Command] is all over this, but our ability to do much about it is very limited, short of dropping bombs on them."

Sky News says it obtained the footage from the Free Syrian Army, which found eight hours of unedited video on a captured ISIS trainer. U.S. officials declined to comment on the specific claims in the video, but did not dispute the claims or the authenticity of the video.
