Cannons?

[zackmann08]

Seemed to me that this sort of weapon rarely, if ever got its own page. Are there any other examples of artillery on the site??

Directly from the Rules, Standards and Principles: "What we do not allow are weapons which are too large to be operated by either an individual or small crew or are used primarily as indirect fire delivery systems. This disqualifies fuel air bombs, all air dropped bombs, mortars, artillery, IEDs, most explosive ordnance."

Artillery is specifically mentioned therefor it doesn't qualify.
