For those a bit daunted by the terrain, the only way to concievably put out targets is to fly a mission, enable your DisplayDebug=TRUE and use CTRL + F12 and then "fly" to where you want. If you get something like the image below, your targets will be sunk "on the earth" and therefore not reachable technically by your weapons due to collision zones and "transparency" of the 3d terrain. However, you can also find areas that if you "fly" and you are skimming the ground, without getting the result below, then you can put targets on there. I found that out today with a SAM site on the slope of the mountain, so technically... you should be able to engage those targets without sinking them.
