Battlecry like the ability? or the Thu'um
The ability is a racial trait, The Altmer have Highborn, Orcs have Berserker Rage...... etc
I believe he means audible battle cries, not abilities, like what we here when we fight certain Nords or Stormcloaks in-game. To answer your question I suppose it would depend on the situation if and if it merits it.
