During the Big Shell Incident in 2009, the B.D.U. saw use by Gurlukovich soldiers in the Shell 1 Core of the Big Shell offshore facility. The Cyborg Ninja Mr. X provided one of these uniforms to special forces agent Raiden, with which to infiltrate the Core, despite the uniform's small size being less than ideal for him. After procuring an AKS-74u to complete the disguise, Raiden succeeded in bypassing the security measures in the Core, but was later captured, and his balaclava confiscated. Though he was ultimately rescued by Mr. X, Raiden was unable to use the B.D.U. any further.
Behind the scenes
The B.D.U. is an item that appears in Metal Gear Solid 2: Sons of Liberty. While both the B.D.U. and AKS-74u are equipped, the player should not do anything to attract attention (such as crawling or rolling) and not un-equip either of the items. Bumping into guards will cause Raiden to accidentally un-equip the B.D.U. After the balaclava is lost, the B.D.U. still has its uses-- for example, if Raiden has caught fire, equiping it and then unequiping it will put the fire out. Additionally, the B.D.U. can be used to cover the player's tracks if traversing through areas where footprints can be left behind.

Same uniform as Shell 1 Core Gurlukovich soldiers. Equip AK at the same time to disguise as enemy soldier. (Equip to wear. Balaclava is no longer present.)"

If Iroquois Pliskin is contacted while the player is wearing the B.D.U., he will comment that Raiden's "walk" won't blow his cover, in reference to how he located a disguised Meryl Silverburgh in Metal Gear Solid.
Although the specific B.D.U. in Metal Gear Solid 2 does not make any reappearances in the Metal Gear series, B.D.U.s in general were a clothing option for players in the second version of Metal Gear Online under the Chest category of clothing. As such, it contained multiple colors and camouflage patterns. Similarly, B.D.U.s themselves do not appear in Metal Gear Rising: Revengeance, although they were mentioned in the description for the Commando Armor as a comparison.
