If you are from a real military like the US, UK, Canada, etc., you use your standard issue stuff and get issued a few items like a blue helmet cover, some patches, and so on. You may also have rules dictated stating that certain items of your standard issue like machineguns and grenades are not allowed. If you are from a 3rd world country like pakistan, they show up with the clothes on their back and a weapon in their hand. The UN will give them everything else they "need" for the mission: Ind. equipment, rations, comms gear, ammunition, clothing, vehicles, computers, and so on- and much of the time, they will either be allowed to keep the stuff, or it will become "lost". Not to mention actual $ paid to the government of that UN member, I assume for the trouble. This is how and why you see UN troops from somewhere like pakistan deploying to somewhere like haiti to "fix problems". Sometimes, the country they deploy to is just as bad as the one they left, maybe even better.
