Hammer Two-Six was the callsign of a UH-60 Blackhawk helicopter that extracts the SAS team in "Blackout". It is shot down by a enemy Stinger missile in "Hunted", killing the two pilots and Paulsen.
The pilots in the helicopter at the end of "Blackout" are Russian Loyalists, but they have American accents, as well as written in the tail "Royal Air Force". At the beginning of "Hunted", they are wearing SAS uniforms.
In "Hunted", there is a mistake in the pilots' mayday call - the helicopter is referred to as "Hammer 6-4".
