Use of P90 in US Military?

Just a bit curious here. I know the P90 is a type of weapon, but are there any specific branches of the U.S. military that have used the P90? Any information would be cool.

The FN P90 is indeed a very distinctive type of weapon, known specifically for its personal defense weapon (PDW) design, compact form, and high-capacity magazines. The P90 is typically used in situations where a pistol isn't enough, but a rifle would be too bulky or unwieldy. It was developed by the Belgian company FN Herstal for NATO during the late 1980s and early 1990s.

In terms of its use within American military forces, the P90 has seen some application, although it is not standard issue across any of the six branches. The U.S. Secret Service, which isn't technically a branch of the military but, nonetheless, a federal law enforcement agency, is probably the most well-known American entity that employs the P90. This is because the weapon's small, compact design makes it discreet and efficient for the type of close-protection tasks this agency is often required to undertake.

Within the military itself, the use of the P90 seems to be less prevalent and more specific. Elite units, such as the special operation forces, have been occasionally reported to use the P90. The main characteristic of the PDW that benefits these military users is the weapon's ability to penetrate body armor, which can be particularly useful in certain combat scenarios. However, in more general terms, the M4 Carbines and M16s tend to be the standard issue rifles in most U.S. military units.

Please note that this is not the official standard across all U.S. military branches, and particular regiments or special units may have their specific stipulations for weapon use and procurement. Complementing this, the P90's use can also depend on the nature of the mission or operation at hand.
