I've just started looking into something that's been bothering me with the British Regulars in the 75 campaign. Can anyone tell me what the design decision behind giving most line units light and/or grenadier companies in the game? As far as I can tell, the British Army (and possibly the German contingents under their command) detached the light and grenadier companies from their parent battalions. That is to say, a line battalion was composed of one grenadier, 1 light and 8 line companies. The light companies were detached and regrouped in separate light battalions, the same happened with the grenadier companies. So in game terms, no British line battalions in the 75 campaign should have light or grenadier elements and be formed of only 4 line elements.
Note that there also seem to be some issues with the strength of the light and grenadier battalions in those scenario setups (resp. reinforcements), also with the marine battalions. While I don't have any reliable numbers for the strength of light, grenadier and line companies, it would be reasonable to assume that grenadiers would make up 1/10th of the infantry, idem for light. Gage's force at setup of the 75 campaign has a total of 30 infantry elements, 2 grenadier, 2 light and 26 line, with Howe's reinforcements that's increased to 2 grenadier, 2 light and 43 line. That makes for only a ratio of 0.425/10th of the infantry in the light and grenadier units, so less than half the expected strength. There are also only 2 elements of marines in a single battalion when I find that by May 1775 two battalions were ashore at Boston with a total strength slightly less than 1200 men (all ranks). Note that I also don't understand why the 1st and 2nd Light battalions were relabelled at some point in WiA (or was it already in BoA I ?) to two of the line battalions present at Boston at the time. Lastly, the total infantry strength in Gage and Howe's Forces seems to be pretty low with 6120 men when one would expect something closer to 9700 men (marines included) (well actually less as that would assume full strength).
I'm considering to mod this into a new scenarior, but maybe there was a good reason for the current representation in WiA.
