These BMPs replace the original 'sand' and 'arid rocks' terrain so that there is a grid superimposed on the ground. This makes it easier to see the contour of the landscape. I used a light grid on the sand textures and a dark grid on the arid rocks textures. (I found that the light grid didn't show up well on the arid rocks.)
I didn't create a set of tiles for the 'dirt' terrain used in Italy, since the CMBB grids work great on those. I got my set from The CMHQ Grid Terrain section. (You want to replace files 1550-1569.bmp.)
To install, unzip these files into Combat Mission Afrika Korps/BMP and choose to replace the existing files. It is HIGHLY recommended that you back up files 1830.bmp to 1869.bmp before overwriting the files.
I have no affiliation with battlefront.com, Big Time Software, or the Combat Mission series. Thanks to the wonderful guys at battlefront.com for creating such great software and supporting the mod community.
