A quarter of America’s active-duty troops are worried about what orders President-elect Donald Trump will issue, according to a poll released Friday.

Twenty-seven percent of service members polled said Trump would negatively affect their jobs or missions, according to the Military Times/Institute for Military and Veterans Families (IMVF) survey.

One in 5 troops, including a majority of those who voted for Democratic nominee Hillary Clinton, said Trump as commander in chief would make them less likely to re-enlist.

U.S. troops are also skeptical that Trump can end the 15-year conflict in Afghanistan during his presidency, according to the poll, with 28 percent saying he can achieve that and 34 percent saying he can’t.
