Shortened form of 'umpire' used by baseball players, managers, and anyone connected with the game.
Fans don't call umpires 'umps'- they usually use more offensive names.

An aconym for Universal Machine Pistole. I weapon that fires a 0.45 ACP round at a RPM rate of about 500. Some would call this Slow for a Submachine Gun of the 90's, but when examined closer, the higher caliber of the slug makes the delay all the more worth it.
A 25 round stick magazine protrudes from the bottom of the gun's body and a small muzzle with grooves for a silencer sticks off the front.
Over all, a Wonderful weapon in Real life.
However, the Developers of games Like Counterstrike have Butchered the True nature of the Weapon and made it second best to it's baby brother, the Mp5.
(even so, I'll still use and WIN with my UMP)
1) That's a nice SOCOM silencer you've put on you're UMP 45.
2) 45 ACP: Finaly got a decent rampage with my UMP

A sub machine gun developed by Heckler and Kosh, the same company that has made the MP5 series and USP.
Developed due to the low penetrating power(against armor) of the MP5's 9mm ammunition and high cost. In fact, in enforcement agencies the MP5 submachine gun is more expensive than a M4A1 rifle.
Also, in real life the UMP is much more easier to clean than the odd MP5 which needs special tools.
Overall, the UMP is much superior than its brother, the MP5. It has power, low cost, accuracy and reliability. Could you ask for more?
