Thousands
of
tons
of CS
gas
were
reportedly
used
by the
U.S.
forces
in
Vietnam
to
bring
the
Viet
Cong
into
the
open.
It was
also
used
by the
North
Vietnamese
forces
during
fighting
in Hue
in
1968
and
the
Easter
Offensive
in
1972.
At
today's
Overlord
Show
near
Portsmouth
the
'Wolfhounds'
recreated
the
use of
CS
Gas.
