Warrior Ancient and Medieval Rules

[John Murphy]

My understanding of the rules is that troops which are
interpenetrated are unable to shoot in the same phase.

So LI evading lancers or routing from them through massed 4/stand
shooters (a legal interpenetration hence one they would not or could
not avoid) would cause those troops to be unable to support shoot
when the lancers hit them (converted charge, pursuit or simply a
charge against a new target). Furthermore it is likely if the
lancers charged impetuously that they would still be considered
impetuous when they hit or pursue into the uncovered massed shooter
target.

On the other hand, depending on circumstances the shooters, if loose
order, may get to avoid a waver test this way, right? If the contact
happens as a result of the LI evading through during a charge
response _then_ I think the loose order would have to test, would
not get to support shoot, and would be in the worst shape against
impetuous charging lancers counting L factors. If it happened as a
result of pursuing routing LI then it is a pursuit so no charge
responses meaning no waver test, and no L factors although the
lancers would get 1.5 ranks and probably still impetuous.

So my question is - is this a real bad idea for mounted to use enemy
LI as a shield against the massed shooters behind them?

Of course, maybe there are better ways to do this! But given a lot
of support shooters that you are having trouble closing with and not
the best tactical situation maybe this is not a bad way to avoid
being support shot down 6 or something horrible like that?

Comments, suggestions? Especially do I have something missing with
the rules in this?
