I think someone on this forum mentioned in a post last year that the OD concept could be taken a step further and integrated with the distribution of fabric paint/ spray to allow customisation at the lowest levels. If the fabric paint was relatively temporary and washed out or faded after a few days of wear then that's no problem, reapply when possible. For recognition purposes it could be applied through a cut-out template to preserve uniformity. It wouldn't be parade-ground pretty, but it would be a darn sight cheaper than the patented stuff and would be limited in effectiveness only by the adaptability of the soldiers and organisation employing it. Again, I think someone else on this board raised this idea first a while back so there is no originality here on my behalf. I do, however, think it holds merit.
