Each front-rank man then inserts the muzzle of his rifle under the front end of the tent and holds the rifle upright, sling to the front, heel of the butt on the ground beside the bayonet. The rear-rank man comes to the front of the tent and pins down the two front corners on the line of bayonets, stretching the sides of the tent taut. He then inserts a pin in the loop of the front guy rope and drives it in the ground at such a distance in front of the rifle as to hold the rope taut. Then both men proceeding to the rear of the tent, each pins down a corner, stretching the sides and rear of the tent taut before driving the pin in. The rear-rank man next inserts an intrenching tool or a bayonet, in its scabbard, under the rear end of the tent, the front rank man pegging down the end of the guy rope. The rest of the pins are then driven by both men, the rear-rank man working on the right. The front flaps of the tent are not fastened down, but thrown back on the tent. In pitching the tent, it is absolutely necessary that the front-and rear-rank men work together. Team work is essential. When the camp site is small, it is necessary that each [Illustration: Arrangement of Field Equipment in Shelter Tent Elevation] company pitch its tents in two lines facing each other. The following illustration shows the arrangement of the articles of the equipment when they are laid out for inspection. During the inspection, each man stands at attention in front of the corner pin of his own shelter half on a line with the front guy rope pin, unless ordered to the contrary.
