I just want to test that my basic understanding of the army is up to scratch. Iâm writing this from memory, could you please check if Iâve made any mistakes or missed out anything important. There are 30 soldiers in a platoon, commanded by a Cpl, Sgt, and a Lt. There are 3 platoons in a company. A company commanded by a Cpt as 2IC, and a Maj as OC. A battalion consists of 3 companies, 1 support company, and HQ company. A Lt. Col who is the CO commands a battalion. There are numerous battalions in a brigade, and numerous brigades in a division. The teeth arms of the army are the infantry, the royal armoured corps, the royal artillery. Combat support arm consists of the royal signals, AAC, REME. Support arm consists of AGC, the medical corps, queen Alexander royal nursing corps, dental corps, veterinary corps, the RLC. Ok so where have I made mistakes? Thanks for any and all help.
