I too have a few, .......
FMA was actually RCT related (The Black Adder) of 10 Regiment Group RCT (1st Gulf War) The CO was given the task of designing a formation badge and asked his son if he would like to help him and his son said "Do you have a cunning plan daddy "?
Which is why the Forward Maintenance Area (FMA) had the Black Adder, which was right facing and black merrow edged only.
This has continued into the 101 Loggies Brigade, as you can see
