The guys from the Japanese Gungineer Airsoft Forum and Gunsmith Engineer gave the DCS A-TACS FG BDU made by Propper International a video test. What they find about this is that it's close to multicam, and being lighter shade of green, it's bright in forest or bush, but quite effective in grass. In dark places it's a dark spot depending on your viewing angle.  Well, movement still reveals the user but then, concealment means that you should not move to make the pattern more effective as eyes quuickly react to movement.

Thanks to Hiro for the video link.
