going for anything but stuar is poinless because of 222s
No, this mindset is bad.
Grab an M20 or an AA halftrack and you'll be able to seriously threaten his sniper. The key is to get weapon racks and get a couple bazookas to deter the 222 from engaging. (Or a bofors to hide behind, but getting in the habit of getting weapons early is better.)
My suggestion would be for both players to get relatively early weapon racks and some AT weapons to hard counter the 222, allowing their light vehicles like m20 or universal carrier to deal a lot of manpower bleed and threaten the sniper. The American AA halftrack is also extremely hard to deal with when used properly before you have a pak so take advantage of that.
Also, anyone building double sniper will have other weaknesses. He won't have as many units to cap on the flanks for example.
