this content of this information card was seen as vitally important and all soldiers were taught to be entirely familiar with it as it contained specific instructions to be followed when opening fire on a suspected enemy. requiring, "total understanding and instantaneous recall of the provisions..." warnings were to be issued to allow suspects to surrender. soldiers could only shoot without warning "if there is no other way to protect themselves or those whom it is their duty to protect from the danger of being killed or seriously injured." the card was amended in 1980 to carry the words "firearms must only be used as a last resort". the use of the card was debated in parliament.
