When this Mycenaean (and/or Trojan) army was first started several years ago, the Tereta spearmen were originally based in three ranks. Then, as now, I think they look better in three ranks. So, this change will only necessitate me getting new movement trays from them. Since they all are on Litko magnetic-bottom bases, I need to have the trays lined with either sheet metal, or steel paper. I'm still undecided to go with either Litko or RenInk. Both, good sources for what is needed.
For the Tereta with thrusting spears and large shields, I had to drop one integral archer - the unit was previously at 28 figures; now they are down to 27 - three ranks of 9. The ratio for integral archers is 1:3 spearmen. So, to be true to the rules, they now have 6 archers - even though the actual calculation is closer to 7 (6.75). They'll get more good skirmisher missile support in battle. The standards and musicians were moved to the second rank - not in the new rules, just for aesthetics.
