Body
What are the three primary functions of the rotating band?
Seals the bore, to position and center the rear end of the projectile, and to impart rotation to the projectile.
What is located below the rotating band, and has a square or boat tail design?
The base
What is a tracer?
A small pyrotechnic charge in the base ignited upon firing that burns brightly making projectile visible.

The base plate
What is the secondary function of the rotating band?
Holds projectile in its proper position in the gun after loading and ramming and to ensure that it will not slip back when gun is elevated.
