The military is getting pulled into the presidential election fight between Donald Trump and Hillary Clinton, which some fear is harming its reputation and ability to serve the future president.

Retired, high-ranking military officers have been given high-profile roles in the Trump and Clinton campaigns, which critics argue risks harming the military’s status as an apolitical institution that serves the commander in chief regardless of party.

Retired Army Lt. Gen. Michael Flynn, an ardent Trump supporter and adviser, and Retired Marine Gen. John Allen, a Clinton supporter, were both given primetime speaking slots at the political parties’ recent conventions.
