Wow. That is called dedication. I was going to do something more in depth..but nice. I love this- it is excellent knowledge, and deserves to be added to the OOC I feel.

The Sterling was a pretty loved weapon in British service even in this period- while shitty, it was excellent at CQB, and was basically an uprated Sten- and in Port Said, the Royal Marines will use them pretty intensively alongside the  SLRs.

The L7A1 was in trial testing in 1957, but I feel that because the Vickers MMG is effectively a Somme-era weapon (by 1956, it'd be out of most regular service), and not man portable by a Royal Marines helicopter bourne unit, saying that this unit would have the FN MAG would be something I could stretch to. Effectively, since this is late 56, I'll assume any users of this GPMG would be pretty well...effective.

Same with the FN High Power- it's a lingering WW2 stock in the Royal Marines arsenal.
