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. [Illustration: =Fig. 67.=--SOLANO ELEMENTARY TARGET NO. 1. (Actual size. See footnote, p. 250.)] [Illustration: =Fig. 68.=--SOLANO ELEMENTARY TARGET NO. 2. (Actual size. See footnote, p. 250.)] 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_. [Illustration: =Fig. 69.=--A CIRCLE (3 INCHES IN DIAMETER) AND A TRIANGLE (3 INCHES EQUILATERAL) SHOWING THAT THE TRIANGLE AS AIMING AND SCORING DIAGRAM INDUCES CLOSER GROUPING THAN THE CIRCLE BY ALLOWING LESS MARGIN FOR BOTH VERTICAL AND LATERAL ERRORS REPRESENTED BY THE DOTS.] (ii) For elementary instruction in aiming the important six o’clock line--the centre of the base of the triangle--is on these targets an indicated instead of an imaginary line, as in the case of the circular bull’s-eye. More consistent grouping is induced by the triangle owing to the fact that it allows a much narrower margin for lateral errors, while its conical shape and straight base considerably curtail the scoring area for vertical errors off the six o’clock line as compared with the circle (Fig. 69). The triangle, moreover, as an aiming and scoring surface puts a premium upon a _low point of aim_ and from the first inculcates in men, as a habit, this vital principle of marksmanship in war.
