The following section contains information from a previous version of StarCraft II which is no longer valid.
The merc compound was once called the merc haven. The merc haven used to train reapers. Training reapers worked similarly to hiring units from mercenary camps in WarCraft III. There was a maximum number of units "in stock" at any one time with that number slowly regenerating over time. Reapers were inexpensive with a build time of one or two seconds. Four reapers could be bought from a single merc haven in quick succession with another reaper becoming ready to "hire" every thirty seconds.
The reaper throws a demolition charge on the ground; two seconds later, it detonates, damaging friendly and hostile ground units and buildings in the vicinity. A red timer bar shows how long until it detonates.
The mines deal 30 damage + 30 against armored units and buildings. Mine explosions do not detonate other mines and do not deal damage to burrowed units unless the player can detect them.
The mines are very small but visible. They can be hidden by units moving past them.
Above the old merc haven was a holographic woman doing the female night elf dance from Blizzard's World of Warcraft, itself inspired from Alizée's J'en ai Marre dance. Concept art depicts the Lich King in her place.

↑ 6.06.16.2In the current build you cannot destroy D-8 Charges. By that I mean that you can select them, but they are indestructible (they don't have HP like other units do, just like units caught by Arbiter's Stasis Field in SC:BW for example). If you are playing against Reapers though, you can still dodge the charges, as it takes them around 2 seconds to blow up. Kapeselus. 2010-01-29. Reaper Charges.
