OK, there must be a good few of you who are still serving or were at the time that the 'Source Branch' (Sonar/Radar/Gunners etc) evolved into the 'Warfare Branch' (OM's). What is your take on this? Keep in mind that the RN tried to revert back to its source branch roots in some sort of way be introducing the 'Topmast'. Do you think having the separate trades such as UW (Under water warfare), AW (Above water warfare), EW (electronic warfare), MW (Mine warfare) and C (Comms) work better as a whole? Also, if you were source before hand, were you given the oppotunity to switch over to warfare?
