Yup as what the title ask my query is zoom in to view and shoot easily  because it can only zoom out but how can I zoom in?

Btw I got the IL2 GB free version its unlike the Steam one in regards to zooming in and out. Steam version has both zoom in/out but the free zoom in is different - its got no crosshair involved just the forwarded landscape ahead..
