Men's cologne

Men's Cologne is a type of body spray.

History
Cologne is a type of perfume that is suitable for human males. It is derived from the German town of the same name.

During the Peace Walker Incident in 1974, Big Boss and his Mercenary group, the Militaires Sans Frontieres, procured design specs from three soldiers that they recruited via fulton recovery at the Rio del Jade boathouse, along with a hobby magazine.

Behind the scenes
In the Japanese version of Metal Gear Solid: Peace Walker, it was actually AXE Body Spray, which was added into the game by Hideo Kojima as a joke on product placement.

In-game descriptions
"On the battlefield, showers are few and far between. And on that important mission, body odor can be a distraction not only to yourself, but to your brothers in arms. That's where this body fragrance comes in, providing a mild aroma that relaxes both body and soul, allowing you and your comrades to focus on the mission at hand."
