The warlord's at-will "Viper's Strike" has an effect that is an immediate interrupt, so it happens before the enemy shifts. If the warlord gives the granted attack to an adjacent fighter, then as soon as the fighter attacks the opponent, it is automatically marked (Combat Challenge).
Now: the opponent is marked and has still not yet shifted. Does the fighter now get a combat challenge attack when the opponent shifts?
Put another way: Does the fighter get (essentially) 2 melee basic attacks against the enemy that shifts away?
