"The attendance of a 47 Sqn, Hercules, Loadmaster will be required on the day"
So, ABIW by the misuse of commas you and the rest of your Loadmaster mates, a Hercules aircraft and, presumably, the remainder of 47 Sqn will all be required to pitch up. However, if the sentence was written correctly, viz:
"The attendance of a 47 Sqn Hercules Loadmaster will be required on the day"
...then only you are required to don your best pressed grow bag and be on duty!
or,
"The CMC is to provide accommodation for 2 SNCOs, a loadmaster and a flight engineer"
Accommodation for 4???? or....
....just 2 - the LM and FE?
"The CMC is to provide accommodation for 2 SNCOs: a loadmaster and a flight engineer"
Yep, it can all be deduced from the sense of it (not)!
