>Let's paint it a camo or an earth tone, because bright colors would stick out on a battlefield.

>Swords are not at all practical for the ranges in which a realistic mech might engage. Instead, lets make that sword a general purpose machine gun.

>To be more realistic, a mech should have sloping armor to minimize anti armor penetration, so let's ditch these right angles.

>The cockpit of the mech is too vulnerable, has too many moving parts, and is often in an obviously telegraphed location. Let's move the cockpit to a point where it has maximum armor coverage from all angles and make the entry/exit system simpler.

>A mech having hands is not necessary, as in a combined arms scenario a mech would rely on other units specifically designed for manipulation tasks. Let's make those modular hardpoints instead.

>Actually, legs would be a massive vulnerability if shot and would not bring many battlefield advantages. Seeing as they're altogether superfluous if a mech is used in tandem with higher mobility units, let's instead replace them with all-terrain treads.
