it is a common practice where organisation do not want to own a
fleet.
If saf owns a fleet, the responsibility of maintaining falls on
them. this way, SAF can't do what they are supposed to do (fight a
war).
if they lease the fleet, maintanence falls on the owner
instead.
also, SAF will be more flexible in the number of vehicles they
want.
Lease more when time needs it... return when don need.
