It can sometimes be impossible to see everything going on around you in the thick of battle, but fortunately there's now a Mount and Blade 2: Bannerlord mod that gives you an RTS game-style bird's eye view. The RTS Camera mod lets you command units from high above, giving you the situational awareness you'd have in a strategy game like Total War: Warhammer III.
