"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
-Thomas Jefferson et al (The Second Continental Congress)
Primarily shot from the M61 “Vulcan” rotary cannon, the 20MM round is one of the most versatile sized rounds around. Most commonly used as an “anti material” round, they work best against vehicles, buildings and aircraft. The HEI warhead version allows even greater penetration power, killing armored targets just as easy as unarmored.
