The function of the Second Amendment is to guarantee an armed civilian force. The United States did not always have a large standing military, nor is it necessarily likely to have one in future.
The civilians of the Founders' era, and well after, were not only expected to have access to military-class weaponry but at one point were actually required to. They had howitzers then, too...and civilians owned, operated, and went to war with them.
Further, the 1939 "US v. Miller" Supreme Court decision ruled against Miller primarily because it was not shown to the Court that a sawed-off shotgun had "utility as a militia weapon". Note also that the United States Militia is made up of two catgories: "organized" and "unorganized". It is from the ranks of the "unorganized" that draftees are selected, when the draft is in effect.
So as long as a draft is legal, so is owning a howitzer in your backyard.
