When buying artillery, a little goes a long way. Consider having two or three times more infantry than artillery in your attack groups. A 1 to 1 ratio sounds good, until you start taking losses on infantry and your artillery loses its attack partner. But with 8 infantry and 4 artillery, you get 8 attacks at 2, 4 attacks at 1, and you can take 4 losses before your 8 attacks at 2 start getting touched.
