Bear in mind that if you rush Stuka as your first vehicle, you're leaving yourself wide open to any LV to show up or even just being walked off the field by weapons teams etc. Yes you can get rak and find even more inf waiting for you if they've read you (not hard tbh).
It's a very big risk, something I personally avoid if possible. AEC/Stuart/T-70 can kill it very easily and they'll have the fuel for those things because they have the fuel position on your part of the map. (You won't get it in the face of MGs except with a good OST...maybe, maybe not). One successful dive and you're utterly screwed for the next 10+ mins. Seen it happen.
As I've mentioned it, this risk gets very minimized in 3v3/4v4. light tanks are very valnaurable to snares & mines. Just one hit from it will make Allies loose LT for nothing It's very hard to find bypass route without detected in 3v3/4v4, so it requires catching enemy at 100% off guard to catch walking stuka. Especially when they tend to nest in the base except for the time they are shooting.
It can be happened, but very not likely.(Also note that they need to hit 2+ shots to kill walking stuka)
