An estimated 16 million people tuned in to watch “Dragonstone,” the premiere episode of the seventh season of Game of Thrones. Unfortunately, this apparently wasn’t an option for at least one member of the U.S. Air Force, who, in keeping with the general tone of the show, decided to make their anger at missing the episode the last thing their enemies ever saw. “This is for making me miss Game of Thrones” they wrote on a GBU-31/B Joint Direct Attack Munition (JDAM), according to pictures that appeared on social media. Two other bombs in the pictures appear message-free.

Armament technicians can assemble the GPS-guided GBU-31/B with a variety of 2,000-pound class warheads, including the bunker-busting BLU-109/B and the devastating thermobaric BLU-118/B. The Air Force is presently looking to buy new BLU-137/B penetrators to replace the older BLU-109s. You can read all about their various capabilities here. There is nothing in the pictures to confirm where or when the images were taken. However, the three JDAMs are clearly mounted together under the wing of an Air Force B-52H Stratofortress bomber. This is a common loadout for BUFFs flying missions over Iraq and Syria out of Al Udeid Air Base in Qatar. The lumbering bombers touched down in the region to take on ISIS terrorists in April 2016.

The brutal extremists have become infamous for gruesome public executions and torture, widespread sexual slavery, draconian dress codes and other social restrictions, and more, all of which would be right at home in George R.R. Martins’ fictional land of Westeros. The group may not have liked some of the more recent episodes, which feature Daenerys Targaryen and her “air force” of nearly unstoppable dragons.

Of course, writing slogans, insults, and other messages on bombs, shells, and other military hardware is an old and nearly universal tradition. Taunting one’s opponents before and during battle is probably as old as the notion war itself. Bomb and shell casings do seem to provide a particularly good canvas though, since the writing or pictograms are less likely to interfere with any existing camouflage or other important markings.

In addition, when it comes to aircraft, tagging bombs and missiles can be a huge morale boost for ground crews, especially crew chiefs and ordnance technicians, who might not otherwise get to share much esprit de corps with their flying compatriots. By adding their own message to the weapons, these personnel get a direct and visible connection to the mission at hand that anyone and everyone, friend or foe, can see.

It’s not the first time we’ve seen this in Iraq or Syria, either. After ISIS members carried out a series of deadly terrorist attacks throughout Paris on November 13th, 2015, pictures appeared online showing GBU-31/Bs, what appeared to be either 500-pound class GBU-38/B JDAMs or similarly sized laser-guided GBU-12/Bs, and Hellfire missiles, all with the “From Paris, With Love” written on them in English in various styles.
