Fionn, I just looked at the HQ website and was reading your treatise on anti-tank guns. I saw several .JPG pictures that reminded me of a question I had. While playing a PBEM game, I saw several columns of smoke where there was no apparent burning vehicle, forrest, or house. These same columns appear in picture 1.JPG, in your article. From the verbiage I now understand that to be screening smoke. Does and infantry unit's smoke look the same as a tanks? Is there a technique for laying a smoke screen, ie. more than just a point source? Thanks!
