Columbian A-P4 (United States of Columbia)

The Columbian A-P4 (Artillery Prototype 4th Generation) is a artillery from the United States of Columbia built to do massive amounts of spread damage from a long distance. Designed in 2010, it was designed in several stages, until in it reached it current stage, after four series. It was originally to be contracted to Pravus International for construction inside the Columbian Industry Belt, but was revoked after the Comstock Administration turned against the mega corporation.

Use & Information
It was used first during the Columbian-Appalachian War of 2013 when Columbia led a siege against the state of Appalachia, the howitzer was extremely effective in first destroying the Mountaineers air defenses and eventually destroying several fortifications. When Columbia used it against Appalachia's cities defenses it was one of the most life-destructive weapons during the war, news coverage of the bombardments compared it to the carpet bombings of Germany.

It's current producer is Columbian Armor, while not nearly at the size of Pravus, Boeing or any other major companies it has been able to provide the United Columbian Armed Forces with 2,350 units before the planning of the war had even begun.
