Mine Systems. Modular Pack Mine System (MOPMS) MOPMS is a man-portable antitank/antipersonnel (AT/AP) mine system with command detonation capability. It weighs 165 pounds and contains a mix of 17 magnetically fuzed AT mines and four AP mines. Its 4-hour self-destruct command can be recycled three times or command detonated by remote control.
The 13th Amendment to the Constitution of the United States was ratified on this date in 1865. It reads, Neither slavery nor involuntary servitude shall exist in the United States.
In December 1787, Delaware became the first state to ratify the document. On June 21, 1788, New Hampshire ratified the constitution, giving it the theoretically sufficient endorsement of nine states, but New York and Virginia had yet to agree. Without them, the federal government couldn't function.
