Trenches 101

Face-front, face-right,
face-left, face-back;

or better -- just spin, instead.

The goal:  To scan
all four directions

with eyes in the back of your head.

Do it promptly, do it fast,
do it subtly, do it well --

do it over and over again.

Repeat when you hear a branch break

or a rustle round the bend.

Be alert to shadows looming,

especially back-left or back-right.

Listen for unnatural sounds

as twilight fades to night.

Watch your head and watch your feet

and check from side to side:

Basic instinct protocol

when one can't run and hide.
