Explain how pigeons have our military during wartimes

Pigeons have long played an important role in war. They have more ability and speed and were used around 700-800 years ago to transport scrolls and communicate.

Cameras would be strapped to their feet and the pigeons would fly over enemy territory.

The camera would automatically snap pictures so our military could view the enemy.

a. "to practice" is the best phrase to complete the sentence.
