Electronic Arts announced that the add-on will follow this month's 'Close Quarters', and precede the final update 'End Game'.
Earlier this week, it was reported that Battlefield's premium service will launch to coincide with the 'Close Quarters' pack on Monday (June 4).
The Call of Duty Elite rival will cost £39.99 ($26), and allegedly provide players with new DLC and exclusive content drops in the form of in-game items and rewards.
'Close Quarters', an infantry-focused update, includes four new maps, new weapons, assignments and unique dog tags.
Full details of the 'Armoured Kill' pack are expected to be revealed during EA's E3 2012 press conference on June 4.
