Special dinners are served to the enlisted men on Christmas, Thanksgiving, July 4, New Year's Day and sometimes on February 22. The company commander and lieutenants of the company accompanied by their wives and families and other guests visit the dining room and kitchen just before Christmas dinner is served, often remaining for dinner as guests of the organization. In some companies the soldiers are permitted to invite their wives and other ladies to dinner. In some commands, the post commander accompanied by his staff and some of the ladies of the garrison visit all the dining rooms and kitchens just previous to dinner hour. A newly arrived officer on a post and the adult members of his family are usually invited to be in the receiving line at the first regimental function after their arrival. If you arrive at a post at which you expect to remain longer than 24 hours you should check with the post adjutant for rules on calling. The adjutant will also give the normal calling hours in effect at the post or station. You are usually expected to call on the post commander. If assigned to duty there, you would normally call on all of your intermediate commanders at their offices. These calls should be made immediately after the call on the post commander. If unable to wear uniform, an explanation should be made for appearing in civilian clothes. When it is in keeping with local rules, as verified by the adjutant, you should follow the official visit by a social call on the post and intermediate commanders at their residence within 72 hours after your arrival. If the commander is married and his wife is present on the post, it is customary for you to make the visit accompanied by your wife. These calls should be formal and ordinarily last no longer than fifteen minutes. You need not make other calls until the officers of the battalion, regiment or garrison have called on you except that as junior officer you should make the first call on field officers of your organization. It is customary for all officers of a unit or garrison to call upon the commanding officer on New Year's Day. (Again the commanding officer's desire in this matter can be asked of his aide or adjutant.)
