• Blindfolds will be offered.

• The prisoners have a final three minutes with a religious counsellor.

• The commander draws a black mark on the inmate's clothing over the heart.

11.59pm-0000am (2.59-3am Wednesday)

• The commander raises a sword.

• The marksmen take aim and fire when he swishes the blade down.

After midnight (3am Wednesday)
