Based on ‘The Battle of Sittangbad’ by Young & Lawford from Charge! or How to Play War Games
You'll recognise the scenario if you're a SOG member over at Ambush Alley (or indirectly if you're Old School!)
A major Taliban offensive in Helmand has been thwarted by British forces and the resulting counter-offensive has the group running for the hills. The local leader is unwilling to loss his most valuable supplies and has set up a rear-guard operation in advance of the main bridge across the Sittang to give him time to evacuate his headquarters.
