The British Official Historian, Stanley Kirby, wrote that the best-trained and most-experienced British division had been broken up to reinforce Special Force, which eventually absorbed one-sixth of the infantry in South East Asia Command. He judged that had the division been retained, it could have reinforced the Fourteenth Army, making the defence of Imphal and Kohima in 1944 easier. Historian F. W. Perry wrote, "it is difficult to avoid the conclusion that the results achieved by the force did not represent an adequate return for the resources invested". He further argued that the force was too lightly armed to capture strongly held positions or to hold one if captured, and concluded that Special Force "inflicted more damage and disruption on the British Army than it ever did on the Japanese." Similarly, Slim argued in his memoirs that it had been a mistake to break up the 70th Division as it was the only British division which had been trained in jungle warfare, and that it would have been twice as effective as an experienced conventional formation than it proved to be as part of Special Force.
