In 1915 the KAR was expanded by having the three battalions reorganised into standard four-company battalions, which were then brought up to full strength at 1,045 men each. It was not until early 1916 that the 2nd Nyasaland and 5th Kenya battalions [1916–1963] were re-raised, this being due to do with white sensitivities in Kenya about arming and training large numbers of black African troops. Later in 1916 the 2nd, 3rd and 4th battalions were expanded into two battalions each through recruiting in their home areas. It was not until General Hoskins (formerly the Inspector General of the KAR) was appointed to command British East African forces in 1917 that genuine expansion began. The 1st Battalion was doubled and the 6th (Tanganyika Territory) Battalion was raised from "Schutztruppe" of the former German East Africa and then it too was doubled. The 7th was formed from the Zanzibar Armed Constabulary and the Mafia Constabulary. Later in 1917 many other duplicate battalions were created as the first four battalions (now called regiments in the British tradition) each raised a 3rd battalion and a 4th or Training Battalion. The 4th Regiment raised an additional two battalions, the 5th, and 6th through recruiting in Uganda. The KAR Mounted Infantry Unit (on camels), originally part of the 3rd regiment and the KAR Signals Company were also raised.
