The experience you gain may be advantageous - but dont know if being a military pilot will appeal to some airline's.
The reason's being that if say yr ex fast jet or chopper's then i know of at least 5-6 UK airlines that will not accept you as they feel that being only 1-2 crew operation this is not condusive to CRM in the cockpit/and with the c/crew due to the fact that you being used to being a one man operation more or less. - BUT there are also several airlines that will actively recruit from the military, One of the largest being Brittania airways where it is more or less a military flying club with 80-90% of the pilot's being ex services.
hope this helps
