First of all, I apologize for my clumsy English: I write much worse than I read.
Although it is not exactly an errata (maybe it could be considered an errata by omission), I consider it's a surprising lack that has caused great discussions in my near 30 year group of RQ3 players, and that is a standard in modern games:
Why isn´t there an extensive example of a complete combat, with different situations, movements, SR calculations, results, etc?
Particularly, it could be confusing for new players the SR system when there are multiple actions in the same turn: move, attack, weapon change, missile weapons with s/SR fire rate, spells, etc.
Considering how numerous the examples are in other sections, it would be convinient to solve all the doubts derivated from the complex RQ combat system, a good, extensive, one-page ilustration.
