enemy, so friendly small-arms fire will not ricochet
back toward your position. An expedient picket
driver, which can be fabricated locally, is shown in
figure 8-11. Constructed as shown, it weighs
approximately 5 1/2 pounds and is operated by two
men. One man holds the picket in a vertical position,
and the other slides the driver over the picket and
drives it into the ground. Then both men work the
picket driver up and down until the required depth is
reached. Drive short pickets by turning the picket
driver upside down and using the head as a hammer.
Use the bucket of a front-end loader to push U-shaped
pickets into the ground when the tactical situation
permits the use of equipment.
In locations where frozen ground prevents driving
of the U-shaped pickets, use an Arctic adapter. The
adapter is made of steel and consists of a baseplate
equipped with an adjustable channel receptacle and
two anchor pins. Anchor it by driving the anchor pins
through holes in the baseplate into the ground. One
anchor-pin drive sleeve with a driving pin is provided
with each 20 adapters to aid anchor pin emplacement.
When adapters are not available, start a hole with a
