CHARGES: When in use it uses 1 charge per 30 minutes. Each 10 hit points received uses up 1 charge. Batteries may be changed on all except Life Belt and Advanced
Shield. Those two require charging while plugged in at a recharge point.

Life Belt, full Composite and Powered may be used as environment suits.

Armor either directly stops hits from reaching the wearer or adds the divisor number to the wearers Resistance number.
All hits on STO Shield are cumulative per round.
All hits on Points Stopped armor is resolved as individual hits.
All hits on Early, Late and Advanced Shields reduce the divisor by one after the
first hit (similar to multi actions penalty). On any turn that 3 or less hits is received the divisor returns to full strength.

Borgs are never shielded in 1st combat round. All are shielded in subsequent rounds.
All Borg shields are immune to damage once a drone absorbs one hit with no damage inflicted. Changing the weapons frequency starts sequence over.
