and for the command chain together with the CSM, directly subordinated to the company commander (captain) as staff NCOs. The Fourier is also the substitute of the chief sergeant major (Hauptfeldweibel), if considering the command platoon by itself. Israel Defense Forces In the IDF, the battalion quartermaster is also the commander of the battalions support company, known as the battalion headquarters company. In the standing army he is usually a captain, but the role is a major's role. In the reserve army he is usually a major. While most of the staff officers are directly under the command of the battalion commander, the quartermaster has a lieutenant, a logistics officer and a junior ordnance officer (the battalion's ordnance platoon commander) under his direct command. He is in charge of all logistics issues in the battalion and also in charge of the battalion's headquarter's day-to-day life. He is commissioned as an officer by the ramatkal (the army's general chief of staff), and as a logistic officer by kalar (the army's general logistic officer). In large camps and higher headquarters (brigade, division and corps HQ), apart from the staff officer in charge of logistics, there is also a role defined mostly as "camp commander," who is in charge of the HQ logistic issues, ceremonies and parades and discipline. These duties differ slightly in the air force and navy. The ranks of IDF quartermasters vary from sergeant major to CWO, depending on the size of the camp. However, most soldiers refer to him as rasar (the Hebrew acronym for the rank of 2WO) without regarding his actual rank. Quartermasters are identified (in all IDF branches) by wearing a blue-white aiguillette on their left shoulder. Navies Royal Navy In the Royal Navy and Commonwealth navies (Royal Canadian Navy, Royal Australian Navy, Royal New Zealand Navy, Indian Navy, and South African Navy), the quartermaster is the senior member of the gangway staff when the ship is alongside and is responsible for supervising the boatswain's mate and the security of the brow. They are also responsible for steering the ship while at sea. Belgian Navy In Belgium, the naval ranks of quartermaster, chief quartermaster, and first chief quartermaster are used (in French: quartier-maître, quartier-maître-chef, premier quartier-maître-chef). French Navy In the French Navy, Quartermaster () is a junior rank, equivalent to a French Army and Air Force Corporal. The French rank has nothing to do with supplies.
