Bohemia Interactive has released a new tutorial movie for its new stand-alone, expansion pack, ArmA II: Operation Arrowhead - the video introduces the new Artillery Computer feature, bundled with patch 1.54. This feature streamlines the use of indirect fire weapons, making ordering an artillery strike as simple as issuing a move command. All indirect fire weapons can exploit the brand new Artillery Computer. This feature initiates an interface where you can see your weapon, and the associated minimal and maximal ranges on the map. You may adjust your fire mode in the menu to the right and select the target area that your ordinance will strike.
