Please answer the following question: Information:  - Military patrol was a team winter sport in which athletes competed in cross-country skiing, ski mountaineering and rifle shooting. It was usually contested between countries or military units.  The military patrol competition encompassed 25 kilometer cross-country skiing (15 km for women) and rifle shooting. The size of the patrol was four members. The total climb had to be from 500 to 1200 meters (300 to 700 for women). The rules were very similar to modern biathlon. Traditionally the participating patrol had to consist of one officer, one non-commissioned officer (NCO) and two privates. The officer carried a pistol instead of a rifle and did not take part in the shooting. The total weight of the backpacks of the NCO and the privates had to be at least 24 kilograms. In later years the competitors did not carry backpacks, and the rifles were small bore rifles, similar to those in biathlon. The patrol leader did not have any kind of weapon.  - The Olympic Oath (distinct from the Olympic creed) is a solemn promise made by one athlete judge or official and coach at the Opening Ceremony of each Olympic Games.
