Life in disarray with San Diego's capital invested in somewhere medics are fatigued? (5,8)
I believe the answer is:
field hospital
'disarray with san diego's capital invested in somewhere medics are fatigued?' is the definition.
I can't tell whether this definition defines the answer.
'life' is the wordplay.
I cannot really see how this works, but
an anagram of 'life' is 'fiel' which is within the answer.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for field hospital that I've seen before include "Battle zone surgical unit" , "It tries to improve health" .)
