As the evolution of artillery continued, almost all guns of any size became capable of being moved at some speed. With few exceptions, even the largest siege weapons had become mobile by road or rail by the start of [[World War I]], and evolution after that point tended to be towards smaller weapons with increased mobility. Even the [[History of Germany during World War II|German]] super-heavy guns in [[World War II]] were rail or caterpillar-track mobile.

In British use, ''field guns'' or ''light guns'' were anything up to {{convert|4.5|in|abbr=on}} in calibre, larger calibres were ''medium guns'', and the largest calibres were ''heavy guns''.
