"Delta Force: Task Force Dagger is a first-person shooter computer game developed by Zombie Studios and published by NovaLogic. It is a “stand-alone mission pack” to the previous installment in the series: Land Warrior.
Delta Force: Task Force Dagger (DFTFD) places the player in the 2002 Afghanistan conflict. The player is given a choice to be any one of ten Special Operations units (below). These forces are the actual Special Forces units deployed in Operation Enduring Freedom. Each team has a special role. For example, Seal Team Six’s role is that of medic, Green Berets are heavy weapon specialists, and CIA Special Activities Division members are snipers. Though each unit has preferred weapons, the player can outfit themselves with whatever weapons they choose."
