Can be found in the Droid Army Instance, each charge has 6 uses. When the player clicks 1 "use" he gets a dentonator and the mine drops where the player is. Do this to both charges in an area for the Fwrd. Commander Mk.I walks through (more damage)

Put the dentotnators in a seperate tool bar (in total of 12 dento's). When the Commander is called the person that has the dentotnator will rush back as fast as he/she can and set them off when the Commander is on top. It only has 1 shot of making a direct hit.
