UGA's marching band is the Redcoat band. http://www.uga.edu/~ugabands/redcoats/
Speaking from personal experiences I've seen many different marching bands that range in sizes from very small to very large. There are many small bands that contain only 20-30 people total and some bands that contain 300+ members. While those large bands can be really impressive, I have seen numerous smaller bands that were immensely talented and performed just as well if not better than larger bands.

A cell and a marching band are both made up of separate components that need to work together. The cell, with all of its parts like the nucleus, mitochondria, lysosomes, Golgi bodies, ribosomes, vacuoles, etc., need to work together for the cell to work. A marching band is the same. The many different sections like trumpet, baritone, tuba, saxophone, flute, clarinet, percussion, pit, etc. need to work together to create a marching band.
Marching bands can have any kind of animal as a mascot - but goats are particularly common. There are many examples of Goat Majors in the British Army.
