Dust

[PoorOldSpike]

DUST FROM DEMOLISHED BUILDINGS DOES NOT DRIFT WITH THE WIND
PIC 1 - The 105 Howitzer blows the building and raises a dust cloud





PIC 2 - But the cloud stays put despite a strong wind from the east (right to left)

-----------------------------------------------------------------





HOWEVER, dust kicked up by shellbursts DOES drift with the wind as this test below shows.
PIC 1 - I order the 105mm to fire into the ground to produce an impact dust cloud (also note the cloud just in front of the gun caused by muzzle blast




PIC 2 - And within a few seconds the dust cloud has drifted fast on the wind. (dust kicked up by moving vehicles also drifts)


TACTICAL NOTES- Dust is important because it blocks lines of sight.
The above tests all boil down to the following -
Dust disperses sooner or later and never guarantees permanent cover.
The stronger the wind, the quicker it disperses
Big buildings keep their dust the longest
There's a random factor built into dispersal times, so regard all the above figures as approximate only
