The US military has a host of awards and medals for its service members.

Some awards, like the Medal of Honor and the Silver and Bronze Star awards, are given to service members who display bravery in combat.

Others are given for serving in specific operations or even missions — these are known as campaign awards.

Depending on the medals a service member or veteran wears, it's typically possible to determine which wars or regions of the world they have served in.

Scroll through to see campaign awards for operations and missions since the Korean War.

Service members who have supported Operation Inherent Resolve, the US mission in Syria to combat the Islamic State, are now eligible for a medal.

The medal was approved in 2016 — prior to that, service members who supported OIR were awarded the Global War on Terrorism Expeditionary (GWOT-E) medal.

Global war on terror

Global War on Terrorism Service Medal.

There are two different campaign awards for service in the US's war against terror.

The GWOT Service medal is awarded to service members who serve in either a direct or indirect role in support of operations during the global war on terror, including personnel stateside who process paperwork for deployed troops.

The GWOT Expeditionary Medal, seen on the left, is more specific — service members must deploy for service in an anti-terrorism operation. Ground troops deployed to Somalia for over 30 days, for example, would qualify for this medal.

A service member who qualifies for the GWOT-E typically also qualifies for the service medal.

Afghanistan

The Iraq Campaign Medal is awarded to service members who deployed in support of Operation Iraqi Freedom.

For both the Afghanistan and Iraq campaign awards, service members are only eligible for one of each, regardless of how many times they deployed to the country.

Stars may be worn on the ribbons as indicators of participation in specific, designated missions during the operation.

Antarctica

The Antarctica Service Medal and ribbon are awarded to people who spend at least 30 consecutive days in the Antarctic or fly 15 missions into or out of the continent.

The Coast Guard and Navy have Arctic equivalents, which differ slightly but both reverse the color scheme of the Antarctic ribbon and medal, with black or dark blue in the center and white on the outer edges.

Kosovo

The Kosovo campaign medal was awarded to service members who served during the Kosovo Defense Campaign, which began in 1999.

Liberation of Kuwait

Depending on their specific mission and location, service members who participated in the liberation of Kuwait may have qualified for awards presented by the governments of Saudi Arabia or Kuwait.

Operations Desert Shield and Desert Storm

The government of Kuwait authorized US personnel to wear this award if they served in Operations Desert Shield and Desert Storm in the early 1990s.

Other medals depicted here are the Bronze Star, Army Commendation Medal, and Purple Heart.
