Tactical Modes of Units that I played in AoE III are unique ones based on tactical postures as compared to other RTS games where you can switch modes for units to stay up and low, from a regular to the defensive combat postures like the melee ones. Stagger type ones arw more reliable than other sluggish modes for the Infantry. Cavalary tactical modes are not needed their regular modes depending upon their types (melee or ranged) are fine, there a best mode for the cavalary where they don’t chase much outside their radius and come back to their position, which can be done by the infantry through their stagger type modes.
