Above all, the use of standardized abbreviations and jargon made the rules very technical in outlook; this language is known as "legalese" and is in contrast to more "conversational" types of rules. The debate of the merits of both approaches went as far back as the original "Squad Leader" rulebook written by John Hill and Don Greenwood. ASL came down firmly on the side of "legalese", though not coincidentally Don Greenwood was the driving force behind ASL with John Hill having moved on to other projects after the original SL.
