Animals have often found their place on the front lines, serving in wars around the world and demonstrating loyalty, courage, and intelligence that rival their human counterparts. Here are ten animals whose heroic actions cemented their place in history and continue to be remembered as symbols of valor.
1. Sergeant Stubby

Sergeant Stubby, a Boston Terrier, became a hero in the trenches of World War I. Stubby quickly adapted to military life after his handler, Private J. Robert Conroy, smuggled him into France. He could recognize the sound of incoming artillery and barked to warn soldiers, alerting them to don gas masks during gas attacks. Stubby even located injured soldiers in no-man’s-land and captured a German spy by biting his legs. He became the first American dog to receive a military rank, meeting three U.S. presidents and earning multiple medals.
2. G.I. Joe

In the chaos of World War II, carrier pigeon G.I. Joe flew a mission that saved over 1,000 British soldiers in Italy. British forces had just reclaimed a village when U.S. bombers were scheduled to strike it. With no other way to communicate, soldiers attached a message to G.I. Joe, hoping he could warn the Americans in time. Flying over 20 miles in just 20 minutes, the carrier pigeon arrived moments before the bombing and prevented disaster. He became one of the few U.S. animals awarded the British Dickin Medal.
3. Judy the POW

Judy, an English Pointer, was taken in by British sailors during World War II and soon found herself in the brutal conditions of a Japanese POW camp. Judy aided prisoners by sniffing out fresh water sources and barking at guards who threatened her comrades. She provided essential morale, and she was eventually registered as an official POW by her handler, Frank Williams, granting her the same protections as human prisoners. Judy’s courage and loyalty earned her the Dickin Medal, honoring her role in keeping spirits up through dark times.
4. Cher Ami

Cher Ami, another carrier pigeon, flew for the U.S. Army Signal Corps in World War I, carrying critical messages during battles in France. His final mission involved flying through heavy fire to deliver a message from an isolated battalion. Despite being shot through the breast and losing a leg, Cher Ami reached his destination, helping to save nearly 200 soldiers. For his sacrifice, Cher Ami was awarded the French Croix de Guerre. His stuffed body is displayed at the Smithsonian.
5. Wojtek the Bear

Wojtek, a brown bear cub adopted by the Polish II Corps, grew up among soldiers during World War II and became a trusted member of the unit. Known for his playful antics and love of cigarettes, Wojtek helped carry heavy artillery shells to the front lines in Italy, often walking on his hind legs to do so. This remarkable feat cheered up the soldiers, who officially enlisted Wojtek as a private to ensure he received his rations. After the war, Wojtek retired to Edinburgh Zoo, where he was frequently visited by his former comrades.
6. Sergeant Reckless

Originally a racehorse called Ah Chim Hai, Sergeant Reckless was purchased by the U.S. Marines during the Korean War and trained to carry ammunition across battlefields. She performed her duty tirelessly, even while injured, and learned to navigate dangerous terrain on her own. She was also famous for her endearing personality and a taste for scrambled eggs and Coca-Cola. Reckless earned the admiration of her regiment, rose to the rank of staff sergeant, and ultimately retired with full military honors.
7. Seacat Simon

Simon, a scrappy stray cat, found his way onto HMS Amethyst and quickly became an important crew member. During the 1949 Yangtze Incident in China, Simon—though wounded by enemy fire—continued to hunt the rats infesting the ship, protecting the crew’s precious food supplies. Simon’s efforts earned him the prestigious Dickin Medal and recognition as the only feline to receive this honor.
8. Jackie the Baboon

Jackie, a baboon, accompanied his owner, Private Albert Marr, to the front lines during World War I with the South African Infantry. Jackie was trained to march and salute and even alerted soldiers to incoming attacks with his sharp senses. When injured by shrapnel while building a shelter, Jackie’s dedication to the regiment earned him the respect of his human comrades and numerous medals for bravery. His loyalty continued beyond the battlefield as he became a treasured mascot.
9. Rip the Search and Rescue Dog

Once a stray, Rip was a terrier adopted by London air raid wardens during World War II. He quickly developed an extraordinary talent for finding people trapped under rubble after bombings. Without any formal training, Rip sniffed out and rescued more than 100 people from the wreckage of the Blitz, his efforts sparking the formal use of rescue dogs in post-bombing search operations. Rip, too, was awarded the Dickin Medal for his contributions.
10. Winnipeg the Bear

Winnipeg, or “Winnie,” was a black bear cub bought by Canadian soldier Harry Colebourn before he deployed to Europe during World War I. Winnie became a beloved mascot for soldiers stationed in London and was eventually gifted to London Zoo for safekeeping. There, Winnie met a young boy called Christopher Robin Milne, inspiring A.A. Milne’s iconic Winnie-the-Pooh stories and making her a unique blend of military mascot and children’s literature legend.
11. Siwash

In 1943, Francis Fagan won a raffle and got an unlikely price – a duck. They named the duck Siwash, and it became a mascot that would storm the beaches with the Marines. One story was told where Siwash engaged in combat with a Japanese chicken.
12. Tirpitz

Tirpitz the pig is one of the only animals to have been a mascot for both sides of World War I. She was a mascot for the SMS Dresden but unfortunately went down with it after she was left on board. The pig, however, wouldn’t go down without a fight and swam to safety, where she was picked up by the HMS Glasgow and made a mascot for the British.
13. Sergeant Bill

In the village of Saskatchewan, Canadian soldiers saw a young goat pulling a cart. They spoke to his owner and adopted Bill the goat as their mascot. Bill survived his time with the army in World War I and was eventually reunited with his owner.
14. Nemo

Nemo was a brave and loyal sentry dog during the Vietnam War. He saved the life of his handler in 1966 when there was a raid on the Son Nhut Air Base. He was injured in the line of duty and ended up retiring and living the rest of his life at the Department of Defense Dog Center in Texas.
15. Warrior

What’s a man without his horse? Captain Jack Seely wouldn’t have made it home without his warhorse, Warrior. The duo saw the worst parts of the war and even led the Canadian Cavalry Brigade’s charge in 1918. While half of the horses didn’t make it, Warrior made it through the war unscathed.
