Number Sequencing.
Perhaps we are aligning sqn numbers.
Are not sitting with 1-18 active now? Albeit with 16 being a training sqn. I may be incorrect.
It’s simple, makes sense and takes away the inevitable bickering when a new sqn is on the cards. Personnaly, I really don’t see the point in people insisting that 43 or, 111 for example are given precedence.
