Both quests are easy enough if you know when and where to pull. I did both of them by myself. If you are a druid or rogue, the best thing to do is prowl around the areas so you can get a good idea of where people are, where the plans and letters are, and where to run.

Covert Ops Beta - This is a little more difficult than Alpha. The wagon for this one is on a small hill in front of the mine. The mine is located at about 74,58 or so. There are no guards on this wagon, just an operator, and he's far enough away where he won't aggro. Slightly behind the wagon there is a small hill. You can blow the wagon if you stand on that hill and keep the wagon to your right.

The letters for this one are on the right/east side of the mine entrance, on a tree stump. They look like a stack of books.

Here's the trick for this one...the kobolds don't run when you blow the wagon. So, you need to kill some of them before setting the explosives. On the west side of the mine, there is another small hill with three kobolds wandering. Take them out. On the east side of the mine, along the ridge, there are two other kobolds. Take them out too. There is another kobold closer to the letters, but if you attack him you'll draw the attention of everyone else, so leave him alone.

Run over to the wagon (don't let anyone see you!) and set the explosives. Get over to the hill and set them off, then take off running. Head over the hill where you killed the first kobolds, then turn to the mine and get the plans. Then run AWAY from the mine (I went to the east, along the cliffs). The kobold you didn't kill will most likely aggro, but if you stop to kill him the rest of the Venture guys will be back and aggro. Just make sure your health is full and run along the cliffs. He stops giving chase soon.
