Brutus has calmed himself after a turbulent time and he is fully awake when the ghost manifests. The dying flame of his lamp announces the ghost's presence.
A soldier is one who fights as part of a land-based army. A soldier can be an enlisted person, a non-commissioned officer, or an officer in the army.
People in the army are called soldiers. Many modern armies have vehicles such as tanks, airplanes, and helicopters to help soldiers fight on the ground. A soldier may be a volunteer (someone who joins something because they want to), or he may be forced by the government to join the army. Forcing men to join the army is called conscription or draft.
