The chart below shows just how much each member of NATO spent on its military last year.
United States' share is huge. In 2014, the US spent about $582 billion (£400 billion) on military expenditure, almost three times more than all the other NATO states combined.
Across the pond, Britain captured the second largest share with $55 billion (£36 billion) invested in its armed forces. However, this is less than a tenth of what the US spent.
Not all NATO members spent the same percentage of GDP on its military. Germany's $44.30 billion (£23.65 billion) expenditure represents just 1.15% of its GDP, while Estonia's $430 million (£280 million) invested in its military accounted for around 2% of its GDP in 2014.
The set of data was published today by the European Military Network (ELN) in a report on this year's budgets in every member state.
