In Theater of War (at least for the ancients period), each side has six strength points to divide across its battlegroups, with a maximum of four points in a given group. In addition, each side can have three "dummy" battlegroups that represent scouts, raiders, or other small forces that can't stage a full-scale battle.
At the beginning, the orcs have their forces in two battlegroups, while the empire has theirs spread across eight. At this point, we determine the capabilities of each of the battlegroups.
Each of the orc battlegroups rolls up an Average commander. Then the quality of each of the units, for both battlegroups, is rolled up.
Yes, each group has (or, rather, could have) all the units. Which actually show up for a given battle depends on the strength points allocated to the battle group, the cards in the player's hand when the battle is joined, and luck.
Here's the final roster for the orcs. The big mess of numbers are relatively easy to understand -- the first number is their missile attack strength, the second is their melee attack strength, and the third is the unit's morale. A dash means that factor doesn't apply (can't shoot). The numbers are actually the size of dice to roll for that unit; the plusses and minuses are modifiers to the roll. As an example, the archers should not get involved in melee -- they roll a four-sided die and subtract one in melee! (Actually, it's worse than that. The archers can only take the field in skirmish formation, which is an additional -2 to melee!)
The Empire gets more of a mixed bag for its group commanders -- groups B and E get Poor commanders, and group F gets a Skilled commander. The other groups all get Average commanders.
Here is the initial Imperial roster. They tend to have higher morale than the orcs and be pretty hard-hitting.
At the beginning of the campaign (the first week of March), the map looks like this:
Imperial group A (2 SP) is in the fortress; B, C, and D (1, 0, and 1 SP, respectively) are in the major towns and city; E and F (0 and 1 SP) are over the mountains, scouting. Group G (1 SP) is off in the hills to the south (looking for bandits?).
Both of the orc groups (3 SP each) have just entered the map.
Next up: the first initiative of turn 1!
