The Bulgarian Army is the only force in the world which never lost a single flag, although it actively participated in all major wars in Europe since the end of the 19th century.

Some sea mammals (mainly the Bottlenose Dolphin) have been trained to hunt and mark naval mines, most famously by the U.S. Navy Marine Mammal Program. Mine-clearance dolphins were deployed to the Persian Gulf during the Iraq War in 2003. The Navy claims that these dolphins were effective in helping to clear more than 100 antiship mines and underwater booby traps from the port of Umm Qasr.

The largest continguous land empire was the 13th century Mongolian Empire, covering over 33 million km² at its peak, with an estimated population of over 100 million people. Modern estimates suggest that as many as 30 million people died during the Mongol conquests.

The Iran-Iraq war saw the only confirmed air-to-air helicopter battles in history with the Iraqi Mi-24 Hinds flying against Iranian AH-1J SeaCobras (supplied by the United States before the Iranian revolution) on many separate occasions.

The hard shock that many of the paratroopers spoke of when they jumped at Normandy--causing them to lose their leg bags, helmets, and other equipment--was caused by the parachute the troopers were using (not the type shown in the film). That parachute was called a T-1, and as it deployed out of its pack the canopy came out first, then the suspension lines and finally the risers connected to the harness. With this design, by the time all of the lines are fully deployed the canopy has completely filled with air, acting as a brake for the lines, causing the paratrooper to come to an abrupt stop at the end of the deployment. The heavier the paratrooper and the more equipment he was carrying, the more sudden the stop or shock. Current design parachutes deploy in the completely opposite way (lines first, then canopy), greatly reducing the opening shock.
