Can anyone shed any light on how Commando units structure their companies. Such as 40 Commando has A Coy, B Coy, C Coy, D Coy, command and logistics companies. 42 Commando has Reece troop, M Coy and J Coy. 45 Commando has W coy, X Coy and Y Coy 43 seems to be made of groups and troops which I think are R,S,O and 1-6 respectively. 30 Commando seems to be it's own beast with a Y Sqn, Info Ops Sec. Plus a few other things I don't know. Is this list complete? Does 42 and 45 have their own command and logs Coy? Does each Coy have a particular role assigned within 3 Commando Brigade or just their unit?
