I know I started this post about the woods, and not urban fighting, but a point of confusion that came up even in those occupations was direction of travel Vs. direction of tank hull. You would have infantry looking big picture as in we are heading north, north is 12. And then you would have bradley crews saying we made a left onto this street and are now facing west, but noon is still my vehicles hull. So that being said the infantry calls armor for support saying contact 2 o'clock 300 meters, meaning northwestish 300 meters, and armor crews that made a left looking for targets northeastish. I still believe that the opord should specify a true compass reading for noon.
With that statement you just confirmed what I thought. You have not served, other than maybe make believe in Call of Duty or paintball. NO ONE in the military refers to the 12 o'clock position as "noon". Plus we NEVER said "northwestish" it was northwestardly direction, etc..
Direction of travel is always 12 o'clock. Doesn't matter if you are traveling south, north, east,or west. Even if you turn off while deploying the direction of original travel is the 12 position. You may be facing the 9 o'clock position but your right is still the 12 and your left the 6. Exception is if you say "I am taking fire from my
6, the small green building behind Charger 23". I have done this, deployed to engage contact. Have a sighting and called it out, " we have 6 dismounts at the 9 o'clock, they just moved into the 2 story building about 150 meters from MSR, the building with the green shutters on the 2nd floor just north of the side street". Or "we got dismounts at the 11 o'clock with small arms and 1 RPG, they are hiding behind the concrete wall about 300 meters out, they are firing and then ducking back behind the wall." If you are spread out over a large area to clear it out it was, " we have contact to the east north east of my position, the ditch about 500 meters out on the other side of the guard rail". To show location it was also common to mark the target with fire, that is what tracers were designed for.
