wups! somtimes these things get lost in the sheer volume.
Plus BoA is a less frequented 'place' right now, only because of it's age!
IMHO, BoA doesn't 'line up' elements as sub-units as well as AACW [where they are clearly regiments or batteries].
My way of looking at this is taht it's all 'game approximation', where the elements represent the old 'partial losses' of some earlier wargames.
So one element of 4 possible is more like 1/4 of the troop strength.
You can look at the Models [which are are the elements] but they don't really show 'men' lie AACW.
So, a regiment of AME militia [4 elements] is differentiated from a regiment of elite ENG regulars [4 elements] by the combat ratings only.
If you're confused enough, I'll stop for now!!!!!
...and it's not my place to publicize the developing work on BoA2.....
