This augmentation gives this Imperial Sentry Droid a significant increase in combat efficiency in eliminating targets on behalf of Capital Enterprises, but at the expense of it being usable for much else except for combat.

Imperial Sentry Droid has had every external component painted black as night, with attempts to minimize the brightness of external lights and features. This allows this Imperial Sentry Droid to more easily blend into the shadows and darkness unseen.

Imperial Sentry Droid has been modified from standard design parameters to be fitted with reinforced plating. As a result, when compared side by side with the standard Imperial Sentry Droid, Imperial Sentry Droid is found to be more durable while its ability to move has been inhibited.

Imperial Sentry Droid has developed a predatory nature similar to those often associated with assassin droids. As a result, Imperial Sentry Droid will often approach a situation with the mind set of a hunter, and convey their findings as such. This can be disconcerting to others who are unaccustomed to Imperial Sentry Droid.
