Can reapers' charges be killed?

In 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.

D-8 charges don't stick to buildings. You can only throw them directly to the ground and if you target a building they will just appear next to it. They also only damage ground units, so they won't do any damage to your buildings if you manage to lift them off before the charges blow up.
You cannot damage burrowed zerg units if they are not affected by any means of detection. For example if you raid your opponent's mineral line and he burrows his drones you won't be able to damage them without a detector, like for example a Scanner Sweep.

Obviously once again I would like to remind you that this applies to the current build (yeah I know!) :)
