The Company Quartermaster Sergeant was responsible for the company wagon and all the property it contained , including the tents , the company mess gear , the company desk , the company library , the ordnance , the subsistence provisions , and the company tools . He was further charged with overseeing the camp set - up of the tents and picket lines . He inspected the company horses and mules , and reported any problems to the Veterinary Surgeon of the regiment . He was also responsible for acquiring fuel , forage for the horses , and straw for bedding for the company . These were normally drawn from the supplies of the Regimental Quartermaster , along with replacements for uniforms and equipment . When they were not available from stores , the Company Quartermaster Sergeant was responsible for forage parties to acquire them . The Company Quartermaster Sergeant was required to sign for the uniforms and equipment that were in his custody and before disbursing these items to a soldier , he required a signature of receipt , countersigned by an officer . The rank of Company Quartermaster Sergeant was not a command position , although he was required to know the drills , and the duties and responsibilities of the line NCOs . He was the second most senior NCO in the company after the First Sergeant . During combat , his place was safeguarding the company wagon and its supplies . He was generally required to fight only in defence of the company property . In an extreme emergency , he could be used to replace a fallen line NCO , but this was extremely rare . The wagons were driven by Teamsters , who were usually members of the company . Additionally , each cavalry company was authorized a Wagoner with the rank of Corporal . The Company Quartermaster Sergeant wore three chevron s with a single straight tie in worsted . Although worn by volunteer cavalry from 1862 , this rank badge was not incorporated into United States military regulations until 1866 . A Battery Quartermaster Sergeant was also authorised for every artillery battery from 4 May 1861 . They began to adopt the same unofficial chevrons as the cavalry from May 1863 .
