Yes, patriotism means to stand by your country, and you have our gratitude for your service.  Patriotism also means choosing able leaders who will lead wisely.  Giving power to one such as Trump, who admires V. Putin, is to abandon your country to a self-serving demagogue.  Voting for a third-party candidate will take votes away from Hillary Clinton, who has the ability to fill the office of President, and allow Trump to win.
