[1140]. Object. The object of field fortifications is two-fold.
1. To increase the fighting power of troops by enabling the soldier to use his weapons with the greatest possible effect.
2. To protect the soldier against the enemy's fire.
[1141]. How these objects are accomplished.
These objects are accomplished:
1. By means of shelters—trenches, redoubts, splinterproofs, etc., which protect the soldier from the enemy's fire.
2. By means of obstacles—wire entanglements, abatis, pits, etc., which delay the advance of the enemy.
[1142]. Classification. Field fortifications are usually divided into three classes, hasty intrenchments, deliberate intrenchments and siege works.
