A briefing note, published by the General Staff HQ in August 1916, describes the organisation of the Heavy Section MGC. This confirms not only the organisation of each tank company but also their supporting units; the Workshops and the Quartermasters (QM) departments.
Six companies were formed in Bisley; each company consisting of 28 officers and 255 crewmen including reserves. Each company consisted of a HQ and four sections, each of six tanks. Each section consists of three Male tanks fitted with 6lb quick firing guns and three Female tanks armed with Four Vickers machineguns. The manpower in each section was 6 officers and 43 other ranks; therefore each tank crew consisted of an officer and six other ranks (this did not include the ASC driver) with a further reserve crewman per tank.
There was one QM department for every two companies; the QMs department being one officer and four other ranks. The QM for C and D Company was Lt Charles Weaver-Price who deployed with C Company. There was also one Workshops for every two companies; the Workshops was formed from ASC personnel - three officers and 50 other ranks.
The Briefing Note also gives details of the tank's capabilities and limitations warning that tanks should not be used in close woods. Either the document did not reach HQ III Corps or if it did, it was wholly ignored by the Corps Commander, Gen Sir William Pulteney. Despite the pleas of both tank commanders, and the brigadiers whom they were tasked to support, Pulteney directed that the tank be sent through High Wood in 15th September 1916. Despite being commander of III Corps from 5 August 1914 to 19 February 1918, he was not highly regarded. His Chief of Staff described Pulteney as "the most completely ignorant general I served during the war".
