3. OHG (Officers' Mess/"Offizierheimgesellschaft") - Also called Casino ("Kasino" or "Offizierkasino"). Much like the UHG, the "Kasino" also has a constitution, bylaws and a board. Gentlemanly conduct is mandatory: for instance upon entering the main hall, officers are expected to stand at attention and perform a small bow. Additionally, veterans' meetings are usually held either in a UHG or in a Kasino. As with the UHG, Kasinos have permanent personnel, as a general rule enlisted men, called "Ordonnanzen", a military term for waiter or barman. Some Kasinos have grand pianos, and hold recitals, as well as having music played during luncheons or dinners. Official events such as balls and unofficial events such as weddings, informational events and the like, are held here.
