Ancient/Medieval ruleset

Hi everyone.  A while ago someone on this list told me about an
ancient/medieval battles ruleset called Tactica (NOT the one by Arty
Conliffe).  It supposedly came from Australia and was highly thought of
by
the person who mentioned it.  Does anyone remember this or know any
information about this?  Please contact me by email offlist as this is
OT.  Thank you very much.
