The M109 is a Cold-War Artillery Tank, it has a long barrel and a 155 mm cannon that fires HE shells. Although the armor is quite thin and can only survive small arms fire, the M109's cannon is enough to destroy almost anything it encounters on a properly aimed shot. It also has a rooftop mounted .50 cal machine gun. The M109 uses a formal set of words, quite calm and collected on battle as well. Although being all fancy, the M109 still loves destruction.
