Singapore Airshow: Smart soldiers and missiles on display

Back in 2010, defence spending in the Asia Pacific accounted for 20% of global defence spending.

By 2020, that's projected to rise to 33% of the world's total amid an increase in geopolitical tensions.

It's why some of the world's biggest military companies are going all out at this week's Singapore Airshow - Asia's biggest aerospace and defence exhibition.

The BBC's Leisha Chi went to take a look at what's on offer, and talked to IHS Jane's analyst Paul Burton.
