When to use stop and no attack?

These two commands are less used in army micro, but I found they are critical in some cases. My main use of stop is to interrupt trebuchet unpacking when fleeting, and placement of xbows on to the farm. You may move xbows across farms and then stop, otherwise the xbows will attack farms if you click them directly. For no attack, it is important to set it on your secret onagers for wood digging in black forest, otherwise they will auto attack enemy walls and get busted 11.

Do you have other uses for these two commands?
