I would really like to know what was the reasoning behind the 93rd Sutherland Highlanders unit to feature a light infantry company. Not because I disagree with the choice of one unit of light infantry, but because I am quite intrigued by the choice and as to why. Or maybe it's just because for the sake of visual differences and I am slightly overthinking it.

I've looked it up quickly and from the North American theatre of Napoleonic Warfare in 1812, at the Battle of New Orleans, the 93rd (Sutherland Highlanders), 1st battalion, were apparently documented to have a light infantry detachment. This is from Wikipedia for starting research, I would like to know if this can be confirmed.
The British troops overran and captured the American position on the right bank of river while, on the left bank, a detachment of light infantry companies, including that of the 93rd Regiment of Foot, captured some American fortifications. However, the British assault on the right flank assault faltered and the men of the 93rd Regiment of Foot, still on the left bank, abandoned the American fortifications and crossed over to support the faltering right flank.
I would presume that is one example as to why the 93rd ought to have a light infantry company in a new game this time around. I'm only going by what I found and what I presume to be probably true, but not what is cited to be.
Again, I have no complaints with the development, design choice, any of that. I am simply curious what led AGS to make the 93rd a light infantry unit or company as content.
It is only a guess, but I presume the exact timeperiod the game takes place, down to the particular year(s) is somewhere between 1809-1812 or so.
