CHAPTER II. TYPES OF MILITARY AEROPLANES.
Divisions of Service. In the army and navy, aeroplanes are used both for offensive and defensive operations. They must carry out their own work and intentions and prevent hostile craft from carrying out theirs. In offensive operations the machines fly continuously over the enemy's country and attack every hostile craft sighted, thus creating a danger zone within the enemy's lines where no opposing machine can work without being threatened with an overwhelming attack. The offensive also includes bombing operations and the destruction of supply depots and transportation centers. Defensive aerial operation consists in driving out the enemy craft from our own lines, and in protecting working machines when on photographing or observation trips. With a powerful offensive there is of course little need for defense. The former method is a costly one, and is productive of severe material and personal losses.
At the present time there are eight principle functions performed by military aeroplanes:
- Offensive operations against enemy machines.
- Reconnaissance, observation, special missions.
- Bombing supply centers, railways, etc.
- Photography.
- Spotting for the artillery.
- Signalling for infantry operations.
- Submarine hunting.
- Patrol and barrage.
