In the first combat mission in the ArmA 2 main campaign (Mission 2, "Into the Storm") you can rescue Valentina Galkina from getting abused by some OpFor soldiers in a house in Pusta (that is unless you totally miss what's going on in one of the houses). She re-appears in Mission 7, "Manhattan", but so far (at least for me) only as a corpse, with some local policemen on the crime scene explaining that she was caught by a bunch of Chedaki militias and executed on the spot.
Is there a way to rescue her a second time?
