Yes. All of the photos taken in the movie are protected by copyright.
The photos themselves would still be protected by copyright. Whether you were on public or private land at the time has no bearing on copyright protection; however it may affect whether people shown in the photos had an expectation of privacy. In the US, photos taken by the federal government (i.e. by government employees as part of their job) are in the public domain, regardless of where they were taken. Photos taken by individuals not employed by the government are protected by copyright, regardless of where they are taken.
It depends on the circumstances of who took them, when. Your official photo, for example, is not protected by copyright, because it is a work of the federal government. Other photos taken by military photographers, such as are found on DVIDS, are also not protected. Snapshots, on the other hand, taken by someone whose official duties do not include photography, would be protected.
