Agreed - though one should contact the PS&VA (formerly War Pensions Agency) for further information.
If you are unable to work due to disability you can claim your Armed Forces pension (in my day called a preserved pension) early - this is not the same as transferring your pension (so I would agree with Adam).
If you have served in more than one branch of the armed forces it might well be better to have the pensions paid separately as it could end in a higher pension depending on the amount of service and rank in each branch (so make sure you check out this option).
Bear in mind that receipt of pension early can result in loss of benefits in other areas (rent/council tax et al as some councils' assess the pension as 'unearned income'.
I turned 60 a few weeks ago and followed the rules and applied for my pension 3 months prior to my birthday, all went without a hitch. Done 21 years and got my graturity in the my bank account the day before my birthday and tomorrow should see the first of my pension payments
