This will burst a few of your bubbles who like to find meaning and coded messages in the Military Account Tweets. These are put out by Public Affairs Representatives from each unit/station/installation. It is typically a low to mid level enlisted person who writes them which is overseen and edited by officers.
In short, looking for meaning in these releases is equivalent to going to your nearest grocery store and decoding the branding of items on the shelves.
