Watch part two

More than 600,000 troops participated in the Soviet Union's decade-long war in Afghanistan, the USSR's largest military operation since the Second World War.

Yet for many in modern Russia, and in other former Soviet countries, the conflict is one they would rather forget and is regarded with humiliation.

Al Jazeera found that many of those who returned alive are still disappointed by the lack of support they received and continue to bear the psychological scars from a conflict sometimes referred to as the USSR's "Vietnam".

Veterans: Soviets in Afghanistan can be seen from Monday, November 22, at the following times GMT: Monday: 0130, 1230; Tuesday: 0630; Wednesday: 0830; Thursday: 0330; Friday: 0730; Sunday: 0030.
