President Donald Trump has emphasised military might during his first year in office, but the US is not the only country seeking to expand its battlefield capacities. Between 2012 and 2016,more weapons were delivered than during any five-year period since 1990.

Arms sales indicate who is beefing up their armed forces, but head-to-head military comparisons are harder to come by. Global Firepower’s 2017 Military Strength Ranking tries to fill that void by drawing on more than 50 factors to assign a Power Index score to 133 countries.

The ranking assesses the diversity of weapons held by each country and pays particular attention to the manpower available. The geography, logistical capacity, available natural resources, and the status of local industry are also taken into account.

While recognised nuclear powers receive a bonus, the nuclear stockpiles are not factored into the score.

Moreover, countries that are landlocked are not docked points for lacking a navy, though they are penalised for not having a merchant marine force.

Countries with navies are penalised if there is a lack of diversity in their naval assets.

NATO countries get a slight bonus because the alliance would theoretically share resources, but in general, a country’s current political and military leadership was not considered.

“Balance is the key – a large, strong fighting force across land, sea and air backed by a resilient economy and defensible territory along with an efficient infrastructure – such qualities are those used to round out a particular nation’s total fighting strength on paper,” the ranking states.
