A typical Imperial expeditionary Field Force might consist of one cavalry brigade, three brigades of infantry, and a few artillery batteries. A brigade is four infantry battalions or cavalry regiments--in India, usually one British unit and three native units.
A British infantry battalion consists of eight companies, nominally at 100 men each, but usually understrength by twenty percent or more.
The post-Mutiny Indian Army infantry battalion consists of eight companies, as in the British Army. There are six British officers at battalion HQ (commandant, second in command, adjutant, quartermaster, medical, and staff) plus two majors each commanding a battalion "wing" of four companies (after 1874, each wing also has a subaltern). Each company is commanded by a subedar with a jemhadar as second-in-command, and has 5 havildars (sergeants), 5 naiks (corporals), 2 drummers and 75 sepoys. Battalion strength: 8 European officers, 16 Indian officers, 696 men.

Artillery batteries consisted of six guns and about a hundred men, the same size as a company. Field and horse artillery would use 12-pdr or perhaps 9-pdr guns, while mountain batteries would use 2.5 inch screw guns or 7 pounders. Siege work would employ 40-pdrs or mortars.
Four batteries made a battalion--this was purely an administrative grouping rather than an operational one. Batteries were subdivided into two-gun sections.
