The final draft script of "The Andorian Incident" referred to these devices, which are unnamed on screen, as micro-charges. Also, though their quantity is unclear from the episode, the script clarified that Reed used four of these charges.
Similiar to the unnamed explosives in "The Andorian Incident", the charges in "Detained" were referred to as "micro-charges" in the episode's final draft script, despite the fact they are merely termed "charges" in the episode itself. Also in the script, the explosives were set up by Reed, observed by Sajen and another Suliban prisoner, Danik. Sajen criticized the charges, while they were being prepared, as looking "awfully small," though Reed assured him the devices would "do their job." It was Danik, not Reed, who later detonated the charges in the script.
The final draft script of "Countdown" referred to this device, which is unnamed on screen, as a micro-charge.
Micro-charges were at one point intended to appear in "Dead Stop", though they are not actually shown in that episode. In the episode's final draft script, an explosion aboard an automated repair station, set off by Lieutenant Reed, was described as being due to three micro-charges. However, in the actual installment, a large metallicplasma canister, with two blinking lights atop the device, is instead shown to be used.
