I've requested this since I can imagine there are more clans that want their infantry to just navigate using just a map and compass. You'd only need a map and then shift-click where you want to go if hudwp=1, making the compass and gps useless.
But if you put hudwp=0, so the infantry has to navigate properly, the chopper pilots are forced to look on the map the whole time(dangerous) and they can't be as fast as they can/like to be, unless they bring a co-pilot but those aren't always arround.
