Viper 4-1

Viper 4-1 is an MH-6 Little Bird in the mission Down the Rabbit Hole. When Sandman's team moves into the mine's open pit, Viper 4-1 and Viper 6-1 drop off additional reinforcements on the road. 
==Trivia==
*Confusingly, in-game radio traffic refers to a "Viper 4-1" and "Viper 6-1" when coordinating gun runs in the mine pit, though no such helos are seen in game. Viper 4-1 and Viper 6-1 (seen in game as "Viper Four" and "Viper Six") are both unarmed transport Little Birds and are not seen again after dropping off their troops. These transmissions likely should have been made by Angel One, the AH-6 Little Bird that does loiter over the area and provide close air support for the team.
