Table 2.6 Strength of UK Regular Forces by Service, and whether trained or untrained, at 1 April each year
At 1 April 2011, 92.6 per cent of UK Regular Forces were trained and 7.4 per cent of personnel were in training. The percentage of untrained personnel fell from 9.6 per cent in 2010, which reflects the decrease in intake across the three Services (see, for example, Table 2.17).

The total UK Regular Forces strength decreased by 10.2 per cent between 2000 and 2011. The RAF has seen the largest decrease - some 22 per cent, whereas the Naval Service decreased by 12 per cent and the Army decreased just 3.5 per cent. The untrained strength has followed a similar pattern whilst the trained strength of UK Regular Forces has decreased by 7.2 per cent between 2000 and 2011. The RAF trained strength decreased by 21.4 per cent and the Naval Service strength decreased by 8.5 per cent, whereas the Army trained strength has increased slightly (0.8 per cent).

Data from the Joint Personnel Administration System for 2006-2009 have been reviewed and finalised, therefore some figures may differ from previous publications. Please see the Chapter 2 introduction for more details.
