Well as soon as I read that I tried a test game and sure enough tank hunters on the field got their upgrade once it was researched in the supply yard. Am I the only one that didn’t know that? This will make a huge difference in my play style vs PE. I like to keep tank hunters on ambush and hold fire then hit with AT nade first now I don’t have to worry so much about AT guns. Maybe one in the back ground. Pays to read these forums I guess.
