Overseas Loan Service
Allowance (OLSA) – If you are
assigned to a Loan Service
appointment you will be entitled
to OLSA, which is paid via
salary. Those in Loan Service
appointments face a variety of
challenges associated with living
and working in Loan Service
areas. OLSA countries are placed
into OLSA bands. The amount
of OLSA can go up and down as
local circumstances deteriorate
or improve. See JSP 752 Ch 09

Longer Separation Allowance
(LSA) – In addition to LSA
entitlements for those on
temporary duty, if you are
assigned overseas and opt to
serve voluntarily unaccompanied
in a different theatre to your UK
family home, you will be entitled
to LSA Level 1 from the 1st day of
your assignment, and will be paid
at Level 1 for the duration of your
assignment (LSA paid to those
voluntarily separated does not
count towards the accumulation
of separated service to progress
through the LSA level thresholds).
