The recently shown Quiet scene is an homage to Metal Gear Solid 2, Kojima says

On Twitter, Kojima briefly commented on the recently released MGSV:TPP footage featuring Quiet.

“Quiet” scene we unveiled in KojimaStation. I meant to make an homage of SOLID lands on the tanker in MGS2 & Raiden sneaks into Big Shell.”

When you think about it the similarities are indeed striking. Both approach their destination by diving down on it from above. They both turn invisible, and turn visible again as they land on the floor in a crouched position.

As Quiet rises to her feet, she observes the base, similar to Raiden when he arrived on the roof of Big Shell.
