An engineer can defuse mines, satchels, and IEDs. It's possible to order an engineer to repair/defuse something by standing close to it, selecting 'engineer' in your command bar, and then pressing '6-1' ('action' > 'defuse'/'repair'). If you are engineer yourself, simply select 'action' > 'defuse'/'repair' from the Action Menu (default binding is the middle mouse button).
* Artillery Computer - All indirect fire weapons can exploit the brand new artillery computer by selecting it in the Action Menu (default binding is the mouse wheel). The artillery computer 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. The display will indicate an estimated time to target; once you fire the ordinance - by clicking the 'Fire' button - the interface will track each shot. Your aim will change according to your actions once you leave the artillery computer.
