We use that in my small portion of the Army world, and while it mostly is helpful for safety, it can sometimes be a pain in the ass.
Flight of two out of Ft. Drum to KRME - was lead. Weather was sketchy - about 700 ft ceilings. Visibility under the ceiling was fine. Mission had to be done VFR. I reviewed all obstacles along the route and felt comfortable with the flight. The PC of chalk two did not, and questioned it over the radio. Sigh. With the "speak up and let me know" philosophy, I was willing to turn the flight around but sure as hell wasn't happy about it. His concerns had nothing to do with regulations or safety - it had to do with his comfort level flying VFR with low ceilings. From my point of view, in class G airspace we need clear of clouds and a half mile during the day - as long as you know where you are and what the obstacles are, where is the danger? It's what we're trained for and paid to do.
Luckily, right around the decision making time, the weather improved a bit and he got more comfortable. But I really would have turned the flight around if he wanted me to.
