its there first war actually so 2 officers will be added on the mod which is ofcourse Robert E Lee and Ulysses S Grant
fighting mexicans and i forgot this is during the 1846 to 1848 so the guns will still be Muskets but the Artillery will be kinda a bit Upgraded like those guns from North and South but a bit early its called the Flying Artillery so the speed of the Artillery Train will be increased much more like the speed of the Horse Artillery and much more so stay tuned
