The S.H.I.E.L.D. Choppers are a series of helicopters used by S.H.I.E.L.D. agents-

Destruction of Project P.E.G.A.S.U.S.
Nick Fury and Maria Hill arrived to the Joint Dark Energy Mission Facility in the Mojave Desert using one of the helicopters.

S.H.I.E.L.D. Civil War
One helicopter was located at the Cube. When Kaminsky and the other HYDRA agents located at the Cube were outnumbered, they managed to get away with the helicopter and bring it to Cuba.

When Grant Ward and John Garrett had difficulty entering the Fridge, because of the orders the guards were given by Victoria Hand, Kaminsky's helicopter arrived and began firing on them. This made the guards believe Ward's story and allow them to enter the Fridge.

The weapons and other objects stolen out of the Fridge were loaded into this helicopter and brought to Cuba.
