Perhaps this should be another thread topic but I will respond to those comments:
Dave,
I do, on occasion try to deceive with uses of the horizon of bunkers or other forms of earth. I suppose it is conscience. I do use other concepts such as defilade, infilade or echelon in setting up some hazards but I am not sure I am thinking "hmmmm, let me see if defilade would work here" so I imagine it is just training or habit.
Todd,
MacKenzie's experience was in the Boer War where camouflage was a matter of life or death!
Jeff,
Yes, in your case that counts as camouflage, and I imagine you often win the prize for being best dressed anyway.
