Cross-country skiing is a form of skiing whereby skiers traverse snow-covered terrain without use of ski lifts or other assistance. Cross-country skiing is widely practiced as a sport and recreational activity; however, some still use it as a means of transportation. Variants of cross-country skiing are adapted to a range of terrain which spans unimproved, sometimes mountainous terrain to groomed courses that are specifically designed for the sport.
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation.
Orienteering is a group of sports that involve using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. Participants are given a topographical map, usually a specially prepared orienteering map, which they use to find control points. Originally a training exercise in land navigation for military officers, orienteering has developed many variations. Among these, the oldest and the most popular is foot orienteering. For the purposes of this article, foot orienteering serves as a point of departure for discussion of all other variations, but almost any sport that involves racing against a clock and requires navigation with a map is a type of orienteering.
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers.
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system.
Piloting or pilotage is the process of navigating on water or in the air using fixed points of reference on the sea or on land, usually with reference to a nautical chart or aeronautical chart to obtain a fix of the position of the vessel or aircraft with respect to a desired course or location. Horizontal fixes of position from known reference points may be obtained by sight or by radar. Vertical position may be obtained by depth sounder to determine depth of the water body below a vessel or by altimeter to determine an aircraft's altitude, from which its distance above the ground can be deduced. Piloting a vessel is usually practiced close to shore or on inland waterways. Pilotage of an aircraft is practiced under visual meteorological conditions for flight.
The School of Infantry (SOI) is the second stage of initial military training for enlisted United States Marines after recruit training. The ITB now called IMC went from a 59 day course to 14 week course. Since the initial training pipeline is divided between coasts, Marines from areas east of the Mississippi River usually graduate from MCRD Parris Island and move on to SOI at SOI East, while those from the western half of the nation attend MCRD San Diego and move on to SOI West at the Camp San Onofre area of Camp Pendleton in California. Female Marines are trained at both SOI East and SOI West. The School of Infantry's training mission ensures "Every Marine is, first and foremost, a Rifleman". At SOI, Marines with the Military Occupational Specialty of infantry are trained at the Infantry Training Battalion (ITB), while all non-infantry Marines are trained in basic infantry and combat skills at the Marine Combat Training Battalion. SOI marks a transition in the professional training of entry-level students from basically trained Marines to combat-ready Marines.
Survival, Evasion, Resistance, and Escape (SERE) is a training program, best known by its military acronym, that prepares U.S. military personnel, U.S. Department of Defense civilians, and private military contractors to survive and "return with honor" in survival scenarios. The curriculum includes survival skills, evading capture, application of the military code of conduct, and techniques for escape from captivity. Formally established by the U.S. Air Force at the end of World War II and the start of the Cold War, it was extended to the Navy and United States Marine Corps and consolidated within the Air Force during the Korean War with greater focus on "resistance training".
The All Arms Commando Course (AACC) lasts for 13 weeks and is run by the Royal Marines at the Commando Training Centre Royal Marines (CTCRM), Lympstone. Members from any of the United Kingdom's Regular Armed Forces and overseas exchange personnel can attend to serve with 3 Commando Brigade. On completion of the course the successful candidate earns the right to wear the green beret, and to wear the "Commando Dagger" on their uniform. The Royal Marines expect that nearly half of the volunteers will drop out or be dismissed before completing the AACC. The primary aim of the course is to give service personnel the core military skills necessary for Extremely and Very High readiness Commando and Littoral Strike operations.
The Special Forces Group is the special forces unit in the Land Component of the Belgian Armed Forces.
The U.S. Army Sniper Course trains selected military members assigned to sniper positions in the skills necessary to deliver long-range precision fire and the collection of battlefield information. Students will receive training in fieldcraft skills, advanced camouflage techniques, concealed movement, target detection, range estimation, terrain utilization, intelligence preparation of the battlefield (IPB), relevant reporting procedures, sniper tactics, advanced marksmanship, and staff subjects.
Orienteering USA (OUSA), formerly United States Orienteering Federation (USOF), is the national governing body for orienteering in the United States. It is recognized by the International Orienteering Federation and the United States Olympic Committee. It was founded on 1 August 1971. Orienteering USA is a 501(c)(3) non-profit organization. There are 68 current member clubs and over 1,500 members.
Ski orienteering (SkiO) is a cross-country skiing endurance winter racing sport and one of the four orienteering disciplines recognized by the IOF. A successful ski orienteer combines high physical endurance, strength and excellent technical skiing skills with the ability to navigate and make the best route choices while skiing at a high speed.
The Army Mountain Warfare School (AMWS) is a United States Army school located at the Camp Ethan Allen Training Site, Jericho, Vermont to train soldiers in mountain warfare, the specialized skills required for operating in mountainous terrain. It is home to the 86th Infantry Brigade Combat Team. The school is located in Vermont's Green Mountains.
Route choice is a tactic in orienteering and related sports such as rogaining and adventure racing. These sports involve navigation from one control point to the next and, in most cases, the choice of route is left to the competitor. This is provided the rules permit route choice and the course is designed so that a choice exists. In trail orienteering and European style mounted orienteering route choice is not permitted. In United States style foot orienteering, route choice is absent from White courses, limited in Yellow courses, and a crucial element in the design of more advanced courses. Given a choice of route, the competitor evaluates trade-offs among such factors as distance, amount of "climb", degree and extent of "fight", mode of travel, technical difficulty, and the competitor's own preferences.
Mountain bike orienteering is an orienteering endurance racing sport on a mountain bike where navigation is done along trails and tracks. Compared with foot orienteering, competitors usually are not permitted to leave the trail and track network. Navigation tactics are similar to ski-orienteering, where the major focus is route choice while navigating. The main difference compared to ski-orienteering is that navigation is done at a higher pace, because the bike can reach higher speeds. As the biker reaches higher speeds, map reading becomes more challenging.
An orienteering course is composed of a start point, a series of control points, and a finish point. Controls are marked with a white and orange flag in the terrain, and corresponding purple symbols on an orienteering map. The challenge is to complete the course by visiting all control points in the shortest possible time, aided only by the map and a compass.
Foot orienteering is the oldest formal orienteering sport, and the one with the most "starts" per year. Usually, a FootO is a timed race in which participants start at staggered intervals, are individually timed, and are expected to perform all navigation on their own. The control points are shown on the orienteering map and must be visited in the specified order. Standings are determined first by successful completion of the course, then by shortest time on course.
Competitive cross-country skiing encompasses a variety of race formats and course lengths. Rules of cross-country skiing are sanctioned by the International Ski Federation and by various national organizations. International competitions include the FIS Nordic World Ski Championships, the FIS Cross-Country World Cup, and at the Winter Olympic Games. Such races occur over homologated, groomed courses designed to support classic (in-track) and freestyle events, where the skiers may employ skate skiing. It also encompasses cross-country ski marathon events, sanctioned by the Worldloppet Ski Federation, and cross-country ski orienteering events, sanctioned by the International Orienteering Federation. Related forms of competition are biathlon, where competitors race on cross-country skis and stop to shoot at targets with rifles, and paralympic cross-country skiing that allows athletes with disabilities to compete at cross-country skiing with adaptive equipment.
Inuit navigation techniques are those navigation skills used for thousands of years by the Inuit, a group of culturally similar indigenous peoples who inhabit the Arctic and subarctic regions of Greenland, Canada, and Alaska. On the tundra, Inuit hunters would travel for long distances when hunting for game, and on the coastal waters, hunters would travel out of the sight of land, and they would need to orientate themselves to the location of favoured fishing or hunting places, or on the return journey to their dwelling place.
