When I had to do my military service, some 30 years ago when that was still compulsory, all uniforms were drab green and grey (and pretty uncomfortable too).
Camouflage was a word unheard of in the Dutch military at that time (our field jackets had a Velcro closing! Can't get more noisy than that, really).
Suddenly, everything changed to 'camo'; for the (para-)military and the wannabes dressing up in army gear. The picture above is part of the standard German uniform and Army/Navy Stores are stocked to the brim with alternatives.
