I don't know if anyone else has encountered/noticed this but in battle more often than not when commanding any subgroup of your soldiers that ISN'T infantry, the voice line that is played doesn't fully match the order that is given*, but the soldiers ordered will still carry out the correct order.
Ex 1:
Order Given: Archers, move *here*
Voice Line: "INFANTRY, MOVE!"
Executed order: Archers, move *here*
Ex 2:
Order Given: Cavalry, charge
Voice Line: "BOWMEN, GIVE EM HELL!"
Executed order: Cavalry, charge
Yet INFANTRY consistently trigger the correct voice line
Ex 3:
Order Given: Infantry, charge
Voice Line: "SOLDIERS, LEAVE NO ONE BREATHING!"
Executed order: Infantry, charge
*Note: Every now and again the voice line and order given will match up, but this is quite rare
