Military scout sniper slang for "Sophisticated Wild Ass Guess"
Used when there is not enough time to make
proper calculations for the exact shot.
The shooter will make
an educated (sophisticated) guess as to the leading
of the target, the range, wind, etc.
The hostiles were
moving in too fast, I didnt have time
to make the proper calculations, so I just estimated the lead
and range on the target and hit him! - Nice damn SWAG man!
