Saudi Arabia has one of the best-funded defence forces in the Middle East.
The kingdom spends 25% of its budget, or about $80 billion, on its military. That is about double what it spends on health and social development.
It has been throwing its weight around recently, engaging in a war in Yemen and joining forces with Turkey against Syrian President Bashar Assad.
So here's what all that money has bought it.
Saudi Arabia is strong in the air. Its air force contains more than 300 fighter jets and 15 active airfields. This includes dozens of US-made F-15s, with another 80 on order.
The Saudi fleet is also stocked with Eurofighter Typhoons, which are a joint project among European Union members. The country has an option to buy another 72 of the fighters.
In terms of manpower, Saudi Arabia has about 440,000 active personnel in its military, with 225,000 army troops.
