Do I have to do military or alternative civilian service if I naturalise and take Austrian citizenship?

Over the age of 35 you are exempted from military service (Bundesheer) or alternative civilian service (Zivildienst). If you have already done military service in another country that has an agreement with Austria, you are exempted from having to do it again. British citizens naturalising, since there is no National Service in the UK, would have to do military service. Article 37 of the Citizenship Act contains a provision denying people doing military service the right to renounce citizenship to avoid this being exploited as a way out of military service.
