I ran across a couple of options for keybindings that really make a big difference. I listed below the couple of changes I recommend. Are there any changes to keybindings that you use?
Weapons > Zeroing Up = Ctrl + Mouse Wheel Up
Weapons > Zeroing Down = Ctrl + Mouse Wheel Down
Infantry Movement > Combat Pace = W + S
Infantry Movement > Combat Pace 3 Sec = 2XW
View > Zoom In = Shift + Mouse Wheel Up
View > Zoom Out = Shift + Mouse Wheel Down
View → Look Right Down = NUM 3 - This will allow you to look behind yourself. like a quick 180o look. You can still turn and move while looking over your shoulder.
Side note related to keybinding the Remote Designator, Strider and SVD all have the ability to raise and lower their camera with the View > Raise Turret and View > Lower Turret keybinding
