“Normative violations of the nonpartisan ethic by members of the military might not grab headlines like the Marines United scandal, but both have the same net effect of eroding the public’s trust in its armed servants. Updating regulations like DoDD 1344.10 with clearer, more consistent language about political expression on social media is a critical first step in reinforcing the norm of nonpartisanship, and we shouldn’t wait until the next presidential election to do so. Maintaining the military’s reputation as an apolitical institution is at stake.”
