shooting at several ranks

[torbenlouis]

when shooting at unprotected cav unless entirely 1 base deep there is a ++ modifyer.

if the target is light horse - is that unprotected cav?

if 2 lines are BGs of cav adjacent to each other - in 2 lines - 1 directly behind the other -
moving forward together in base to base contact - does this count as
a. 2 deep target i.e. ++
b. 1 deep target i.e. tough luck for shooter

That is from the TT game, and only applies to units classed as Cav not LH. In the PC game not sure how they would designate not being in a single line as there are no formations.
hope that at least partially helped explain it to you
