Um, I might be missing this, but I don't think we're interpreting this correctly. The contract title is Social Media in Strategic Communication, which implies that they're looking at integrating social into their military communications, not creating DoD Facebook profiles or trying to influence public sentiment on Twitter.
From the intro:
1. Detect, classify, measure and track the (a) formation, development and spread of ideas and concepts (memes), and (b) purposeful or deceptive messaging and misinformation.
2. Recognize persuasion campaign structures and influence operations across social media sites and communities.
3. Identify participants and intent, and measure effects of persuasion campaigns.
4. Counter messaging of detected adversary influence operations.
