I'm sure you know as we have gone over this ad infinitum. In the U.S. "assault weapon" is a legal term based on the design and function of the weapon. Not all guns are considered assault weapons nor have all guns been designed for a military assault. An assault with small arms relies on speed of the advance and the rate and accuracy of fire. There are probably thousands of types of small arms not suited for this. For example I have a single shot .22 target pistol, not very effective for an assault.
