Re: British Army L129A1 7.62mm Sharpshooter rifle.
 

When I tested it with Mobhack I had section with SA80, Minimi, UGL plus the 7.62mm rifle. Easy enough to add an AT section or two to a company if there is an armoured threat, or pick a platoon HG with AT.

platoon HG = dyslexic for platoon HQ.

Btw, could I suggest that British Special Forces (SAS and SBS) are very unlikely to use the 5.56mm Light Support Weapon. British SF don't make much use of any SA80 variant (even though the SA80A2 is a vastly better weapon than the original SA80).
