|Covid-19|List of countries by military expenditures Wikipedia
This article is a list of countries by military expenditure in a given year. Military expenditure figures are presented in United States dollars based on either constant or current exchange rates. These results can vary greatly from one year to another based on fluctuations in the exchange rates of each country's currency. Such fluctuations may change a country's ranking from one year to the next.
The 1st list is based on the Stockholm International Peace Research Institute (SIPRI) 2016 Fact Sheet, which includes a list on the world's top 15 military spenders in 2015, based on current market exchange rates. The 2nd list is based on the 2016 edition of "The Military Balance" published by the International Institute for Strategic Studies (IISS) using average market exchange rates.
