Core Dynamics S4 ‘sentry’ skimmer – this is the most widely used skimmer in the vast semi-automated security and protection industry throughout the galaxy, and a mainstay product for Core Dynamics. Comes as standard with a belly-mounted standard recoil-ready small weapon mount, which will take both kinetic and thermal weapons. Designed with an automated alert system so a single pilot can operate multiple drones.
