Could these be 2nd World War tanks which Poland was trying hard
to dispose off with huge discount offers.
At one time M'sia was expressing interest in acquiring them but
citing lack of fund. They even talked about paying through
installments and supplementing the deal with vast supplies of
M'sia's palm oil.
If indeed these are World World II tanks, there is a possibility
that they were built with Russian technology. The weaponry
technology is out-dated for use today. Furthermore, they were meant
for cold climatic European countries - O Kay for cold countries
like Poland but not hot tropical countries in S.E. Asia.
Bringing them over to M'sia, the military engineers may need to
come out with a solution to install cool air-conditioning system,
or else soldiers inside the tanks will be barbequed to death.
Mitsui air-cond system from Protons can be considered.
In cutting down costs, some wise nuts might consider reconfiguring
the system in such a way that cheap palm oil can be used in place
of the more expensive high grade petrol to power the tanks. After
all M'sia is known as one of the world's biggest exporters of palm
oil.
Hopefully these tanks will not leak in water, like those in which
ex-president Habibe purchased out-dated World War II tanks from
Germany. On its maiden journey to Indonesia some of these tanks
leaked in water and reportedly sunk into oceans.
Be sure that these tanks won't end up as museum pieces
