After months and months of moaning coming from the rebel side to make a whitelisted rebel position with bigger weapons, Wilco decided to give it a go.
At first UNMC was a long demanded whitelisted rebel position with only ~5 members(Cant remember excact count), they were selected from the best roleplayers of the server. They had acces to far greater weaponary then the rebel gangs, because they weren't so trigger-happy as some are right now.
Then the demand for UNMC began to rise because of a 2nd server being almost constantly on to forfill the demand of players. This lead to mass recruiting in UNMC aswell as Police. In my opinion this is where it started going down hill, 'newer' players thought UNMC was just a place to kill some popo, some got in because of their application. They were given amazing weapons, remember this weapons were intended to be used to provide UNMC some 'power' over the normal rebels. Now, UNMC has about 40 members and the roleplay is good but it is most certainly not what it used to be.
Then they were renamed to PRNA to make them more like a rebel gang, now they went back to UNMC for some reason. Their base is still under construction and it is just to await what the dear leader decides.
