I think trying to work out a rationale for any given rule is fraught with problems.
Discussing whether reformed troops in buildings would or would not send out skirmishers brings up another (possibly somewhat unrelated) Issue - reformed troops shooting at unreformed.
If you assume that the range of a musket under these rules is 2MU (i.e. close range), then when reformed infantry shoot at reformed, each have their skirmishers at 2MU in advance of the main body of the unit.
This makes some sense, as it puts the opposing skirmish lines 2MU apart.
But when reformed shoot at unreformed, this rationale begins to break down. Either:
1/ the skirmishers have to be shooting at a range of 4MU, or
2/ the skirmishers have to advance to 4MU in front of the main body if the unit, which would place them within 2MU of the unreformed target
which is unable to return fire even though the skirmish line is within range (i.e. 2MU).
In the first instance, the skirmishers have doubled their range. In the second, why can the unreformed target not return fire (at a reduced effectiveness, of course, for shooting at skirmishers)?
Don't get me wrong, I'm not advocating a change to the shooting rules - I'm happy with the way they are.
I just think this illustrates that this is a situation where, short of a clarification from Terry, the rules should be used as written, even where this may seem counter-intuitive.
We've had discussions about this at our club, and apart from instances where a rule is
clarified, we have chosen to not change the rules as written unless included in an official errata.
Too many local changes will end up killing the rules by making it too difficult to get consensus from one group to the next.
As one of our members said, the rules are designed to give a good, balanced game - and will therefore always be an imperfect simulation. This is always a balancing act, and I think these rules get it right.
Having these questions come up on the forum is great, but I think it is important to recognise when an official ruling is required.........
and to get it!
Just my two penneth......
