What do you think is going to happen to the soldier that leaked the pentagon video?

You can't compare the two cases. The pilots may or may not be guilty of an offence and it will have to be determined if their actions were a good faith error, an accident or a willful act for which they are to be held liable. In the case of the soldier who released the video, I doubt very much that he released it "by accident" and he most likely meant to release it which would be a violation of security and as a willful act it is something he will be held to account for.
