Describing traverse
Think of a boxer winding up a punch to hit someone, when the commentator describes him as moving from "side to side" what do you see in your minds eye? Do you see someone shuffling from left to right and vice versa or someone pivoting on one foot. You of course know exactly what traverse means, but anyone who needs the term explained in plain English could be misled.

This is all rather moot I think, as I realise that I have become stuck in a pre-wiki way of doing things, in which descriptions had to be in the text, the ideal solution of course is to remove the description from the article completely and instead provide a wikilink to the traverse section of the gun laying article, where those who need it explained can find a far better explaination than a couple of words in brackets.
