Hi All

Going through the ORB for 83 Sqn in 1946, there are mentions of various exercise/operations undertaken by its crews. Some of these I have come across before but some at new, I wondered if anyone had any definitions for

Ex/Op 'Bombard'
Ex/Op 'Frontline'
Ex/Op 'Victory'
Ex/Op 'Carfax'

Also can anyone confirm that 'Y' Runs were practice H2S bombing runs?
