Fairly new to WoT, just started going through some of the campaigns. The first SPG missions are all about stunning, and no matter what I do, where I hit or how hard I hit people, I never get them stunned. Damaged and tracked, yes, but never stunned. My only arty is the bishop (T5, UK) so that’s what I’ve been using. Any idea what I’m doing wrong or how I can stun people? I’ve played over 20 battles and hit over 45 shots but haven’t stunned an enemy a single time yet.
