§ 19. Sir John Graham Kerr
asked the Home Secretary whether he is aware that the nature and in some cases the individuality of an object of military importance when viewed from a high angle, is betrayed by its characteristic outline; that violently contrasting patches of pigment are effective as a means of disguising outline; that numerous aerial photographs show military objects such as stationary ships and vehicles in which no use is made of such disruptive camouflage; and whether he will take immediate steps to end this ignoring of a basic principle of camouflage?
§ Mr. H. Morrison
The principles whereby disruptive painting may be used to conceal the outline of an object are well understood and are in extensive use where conditions are suitable, but a number of factors influence the decision as to whether such methods should be applied.
