24th anti-spacecraft regimentA surface-to-air missile (SAM) or ground-to-air missile (GTAM) is a missile designed to be launched from the ground to destroy aircraft. It is one type of anti-aircraft (or anti-spacecraft for Star Wars) system; in modern armed forces missiles have replaced most other forms of dedicated anti-aircraft weaponry, with the anti-aircraft cannon pushed into niche roles.I myself was in an austrian air defence regiment during my military service as an observer for an Oerlikon 35 mm anti-aircraft cannon.()I hope you like it gentlemen
