Combat service support in the context of "Netherlands Marine Corps"

Line infantry was the type of infantry that formed the bulk of most European land armies from the mid-17th century to the mid-19th century. Maurice of Nassau and Gustavus Adolphus are generally regarded as its pioneers, while Turenne and Montecuccoli are closely associated with the post-1648 development of linear infantry tactics. For both battle and parade drill, it consisted of two to four ranks of foot soldiers drawn up side by side in rigid alignment, and thereby maximizing the effect of their firepower. By extension, the term came to be applied to the regular regiments "of the line" as opposed to light infantry, skirmishers, militia, support personnel, plus some other special categories of infantry not focused on heavy front line combat.

In the United States Army, the term combat support refers to units that provide fire support and operational assistance to combat elements. Combat support units provide specialized support functions to combat units in the following areas:

• Chemical Warfare
• Combat Engineering
• Military Intelligence
• Security
• Communications

Combat support should not be confused with combat service support. Combat Support units are focused on providing operational support to combat units, while Combat Service Support units are focused on providing logistical support to combat units. Actual combat units are collectively referred to as combat arms units; hence, all army units fall into the category of either combat arms, combat support, or combat service support.

The United States Army Quartermaster Corps, formerly the Quartermaster Department, is a sustainment and former combat service support (CSS) branch of the United States Army. It is also one of three U.S. Army logistics branches, the others being the Transportation Corps and the Ordnance Corps.

The U.S. Army Quartermaster Corps mission is to support the development, production, acquisition, and sustainment of general supply, Mortuary Affairs, subsistence, petroleum and water, and material and distribution management during peace and war to provide combat power to the U.S. Army. The officer in charge of the branch for doctrine, training, and professional development purposes is the Quartermaster General. The current Quartermaster General is Colonel Kevin W. Agness.

The Transportation Corps is a combat service support branch of the U.S. Army. It is responsible for the movement of personnel and material by truck, rail, air, and sea. It is one of three U.S. Army logistics branches, the others being the Quartermaster Corps and the Ordnance Corps. The Corps was established in its current form on 31 July 1942, with predecessor services dating back to the American Civil War. The Transportation Corps is currently headquartered at Fort Lee, Virginia. The officer in charge of the branch for doctrine, training, and professional development purposes is the Chief of Transportation (CoT) and Commandant of the US Army Transportation School, currently held by BG Beth A. Behn. The Corps's motto is "Nothing Happens Until Something Moves".

The Individual Ready Reserve (IRR) is a category of the Ready Reserve of the Reserve Component of the Armed Forces of the United States composed of former active duty or reserve military personnel. Its governing statute is codified at 10 U.S.C. § 10144. For soldiers in the National Guard of the United States, its counterpart is the Inactive National Guard (ING). As of 22 June 2004, the IRR had approximately 112,000 members (does not include all service IRR populations) composed of enlisted personnel and officers, with more than 200 Military Occupational Specialties are represented, including combat arms, combat support, and combat service support.

In military parlance, the rear is the part of concentration of military forces that is furthest from the enemy (compare its antonym, the front). The rear typically contains all logistic and management elements of the force necessary to support the front line forces, and generally constitutes supply depots, ammunition dumps, field hospitals, machine shops, planning/communication facilities, command headquarters, and infrastructure such as roads, bridges, airfields, dockyards, and railway depots.

Military personnel in the rear are usually called the rear detachment, and they are responsible for staffing, supplying, and maintaining the rear elements. The rear is considered a crucial part of military organization, and it can sometimes outnumber the unit's front line force by several times.
