Quiet

Quiet is the forth boss faced in Metal Gear Solid V: The Phantom Pain.

Description
Taking up the entirety of Episode 11: Cloaked in Silence is Quiet's boss. In the wide open fields scattered with ancients Afghanistan ruins, Quiet's boss is a typical sniper fight. First dash from cover to cover and deduce her position by occasionally popping out of cover, revealing an obvious glint from her scope or by tracing her laser-sight. Upon spotting her, quickly aim and fire at her with a sniper rifle (major damage is done regardless but headshots do the most), as she'll quickly retreat to another position, making the player have to re-find her again even if she's marked. Be sure to dive to cover as quickly as possible once Quiet has her sights on you, as it only takes two shots to instantly kill the player. After you do enough damage to her, she'll retreat to a pool around the area's heart where she'll begin slowly healing, leaving herself open for an easy attack. An infamously easy method to defeating her is to mark her, quickly order a supply drop on said marker, and wait for the supply crate to fall right on her head, instantly taking down half of her stamina bar.
