IMHO the most important aspect of the game is initiative and the most important attribute of a TC is to impart initiative to the AC and even the unit commanders that are not stacked with an AC.
The TC initiative has three factors: rank, command rating and administration. You can promote at political point cost and raise command rating through battlefield success. I have not seen anybody's administrative rating rise.
Is it theoritically possible for certain TC candidates to have a 100% chance at initiative!!
Query: Has anybody tried grooming Dix or Meigs through battlefield command experience and promotion to take advantage of that big "6" for admin. For example, if Meigs raised his command rating via battlefield experience to 11 and you promoted him to three stars, his initiative percentage would be 3/4 times 11/20 times 6/6 = 33/80 or 41%. Not great, but certainly far better than Fremont for example. If his battlefield experience continued to grow through successful operations he could become quite formidable; it is theoritically possible to raise command rating to 20 through battlefield success. If you paid the PPs to promote him again to a "4", he would practically unstoppable. So the math is: 4/4 times 20/20 times 6/6 = 100% =
I admit that I haven't determined whether the game would allow all these promotions; I'm just theorizing here.
Also, I haven't checked army modifiers for Miegs and Dix; army modifiers is important as pointed out in an earlier post (I think we have JAMiAN to thank for that insight ).
BTW, if you are ever in Arlington Cemetary, visit the grave of the son of General Miegs. The marker is a fallen soldier covered with his cloak. Very moving.
