Nationwide, many journalists working and writing the news for major TV broadcasts and for wide selling established magazines seem to be under the impression that military members love political candidtaes and civilian officials so much that we give them standing ovations.
If any of these journalists were prior service or even consulted someone prior service prior to publishing, they would know that uniformed members are required to demonstrate military courtesy in uniform and they are ordered to attention.
Attention is a standing pose, eyes forward and involves paying attention.
