Spartan APC Dazzle Camoflage

Using the history of the past could help save lives in todays conflict.  Painting army vehicles with high contrast geometric patterns – ‘dazzle camouflage’ –  derived from past wars affects the perception of their speed and thus could make them less susceptible to rocket propelled grenade attacks, according to new research from the University of Bristol.

Warships in both the First and Second World Wars were painted with dazzle camouflage: startling geometric patterns aimed at confusing the enemy rather than concealing the vessel.  It was thought that such patterning would disrupt the enemy’s perception of a ship’s range, heading, size, shape and speed, thus reducing losses from torpedo attacks by submarines.  While there were good reasons to believe that these perceptual distortions occurred, the effectiveness of dazzle camouflage was never scientifically proven.
