MerrWeapons WorldArmor 4

The MerrWeapons WorldArmor 4 is MerrSonn's encasing shield. It covers a much smaller area than its larger cousin the WorldArmor 9, but is equally as powerful. Its advantages are that it is cheaper, smaller, requires less personnel and maintenance, and is more easily constructed.

As an encasing shield, it is more akin to armor than shields since the unit provides a solid "wall" of protection. However, encasing shields do not allow "friendly fire" to penetrate except through permanently assigned gaps in the energy field. Accordingly, these gaps, called firing slots or fire gaps, are high-priority targets and many of these systems have no fire gaps at all.
