Writing a good set of wargame rules is a complex and tricky affair. Most rulesets go through several rewrites due to the nature of the written word versus intent of the author. Hence, the authors of most good rulesets have a lot of independent play testers play the rules as they are written and provide feedback so they can be revised and clarified before going to the printer.
Even though the playtesting and revisions have taken place, some questions may still arise due to the interpretation of the reader. Hence,most rules follow a similar format no matter who the author or publisher may be. We have to look at those formats from one system to another to help decide the intent of the author if they are not able or willing to clarify the question.
Reading and interpreting rules is something that needs to be done with an open mind. If one person reads a rule differently than another, then it needs to be discussed rationally and if a consensus isn't agreed upon,a mediator needs to make a ruling. The best mediator is always the author as their intent for the rule is what matters!
