2. Elementary Targets (Figs. 67 and 68).—The Solano Elementary Targets have been designed to counteract the tendency to focus the eye on the fore-sight instead of on the target, and may be used for grouping and application practices after firing at the bull’s-eye target. These targets are coloured green, brown, and grey, instead of white, to accustom the eye to the tints of natural backgrounds against which service targets will be seen. The aiming-mark in No. 2 is less distinct than in No. 1, to accustom the eye gradually to focussing on indistinct targets when aiming.

3. Triangle Aiming and Scoring Diagrams.—(i) Triangles have been substituted in these targets for concentric circles as aiming and scoring diagrams, because they have a truer relation to the shape of the human figure in both lying and upright positions. The triangle on No. 1 target has relation to the human figure in an upright position, and the triangle on No. 2 target to the human figure in a lying position. The dimensions of the triangles on these targets correspond with the regulation grouping standards of the British Army.
