So, do I as a voter get a say or are those who have served and been honorably discharged not allowed to vote when the subject is sending troops somewhere?
Of course you do. But it's about as meaningful to criticize people who aren't paid to fight and favor a more assertive stance vis-a-vis Russia as cowards as it would be to criticize them as serial killers or child molesters. It's orthogonal to the point. The military is a tool funded and employed by the people. It is not for the instrument of government policy to call the citizens who fund it cowards or any other epithet that comes to mind.
