GMT's Silver Bayonet Scenario 3 Playthrough

Old-timer noob plays scenario 3 in Silver Bayonet: First team in Vietnam. I did forget to place the "First Fire" marker on the PAVN mortar when it fired at 17:30 . Also, "First" and "Final" fire markers for PAVN artillery are ONLY placed after Offensive or Defensive bombardment, or Maneuver Combat Support. At 20:18 I mistakenly identified the PAVN side as the FWA.
