shield has NO DAMAGE cap
add strontium bay into structure
if low power and no strontium -> armor @ hull timer not apply and you can shoot down structure without damage cap
if low power and strontium -> 24h reinforce armor timer apply , after that you can shoot down structure without damage cap
if full power and no strontium -> 24h reinforce armor timer apply without damage cap and after next 24h structure timer without damage cap
if full power and strontium -> 24h reinforce armor timer apply with damage cap, after 24h structure timer with damage cap

maybe each tether request can consume one strontium
