When humans go to battle, they're often joined by animals — military dogs, horses and even pigeons. These furred and feathered partners in the trenches save lives, sometimes while being injured or killed in the line of duty.

The British charity, the People's Dispensary for Sick Animals (PDSA) awards the Dickin Medal, considered to be the highest animal honor in the world. The organization says the medal is the animal equivalent of the Victoria Cross, the highest military decoration awarded for valor "in the face of the enemy."

So far, 29 dogs, 32 pigeons, four horses and one cat have been honored for "gallantry." The latest is Lucca, the first U.S. Marine dog to receive the honor. Here are some of their amazing stories.

The most recent recipient of the Dickin Medal, Lucca completed 400 missions in her six years with the U.S. Marine Corps in Afghanistan. The search and rescue dog was at the front of patrols with her handler and is credited with protecting thousands of troops. On her last patrol in March 2012, an IED exploded, resulting in the loss of one of her legs. Lucca is now retired and lives with her handler, Gunnery Sgt. Christopher Willingham and his family in California. "Lucca is very intelligent, loyal and had an amazing drive for work as a search dog. She is the only reason I made it home to my family and I am fortunate to have served with her," Willingham says. "Today, I do my best to keep her spoiled in her well-deserved retirement.” Lucca received the medal in April 2016, the first U.S. Marine Corps dog to receive the award.

Bob, a mixed breed, was the first to receive the Dickin Medal in March 1944. He was traveling with his unit in North Africa when he suddenly froze and refused to move. The perceptive pooch saved lives because the enemy was close by. Because of Bob's actions, the men in his unit remained unharmed.

Diesel, the now-famous police dog killed leading a police raid on a terrorist cell in Paris in November, was honored posthumously. The Belgian Malinois was part of the elite French Research, Assistance, Intervention and Deterrence unit. He was part of a siege on a suburban apartment targeting terrorists involved in the Nov. 13 Paris attacks. Diesel was sent into an apartment ahead of officers, where police say he was shot and killed by terrorists, likely saving the life of his handler. His death inspired the hashtag #JeSuisChien ("I am dog") on social media across the globe.

"As guardians of the world’s most prestigious animal awards programme, we were inundated by messages from members of the public to recognise his heroism," said PDSA Director General Jan McLoughlin, on awarding the medal in December 2015. "The PDSA Dickin Medal recognises conspicuous devotion to duty in the theatre of conflict and Diesel is a truly deserving recipient. His gallant actions helped to protect human life in the face of imminent danger, and we are very proud to honour him in this way.”

Four horses have received the Dickin Medal and that includes Olga, Regal and Upstart who were honored April 11, 1947, and Warrior who was awarded an honorary posthumous medal in September 2014. The horses were all members of London's Metropolitan Police Service. Olga and Upstart were honored for courage during active duty, and Regal was honored for staying calm while his barn was bombed two separate times. Warrior's honorary medal was awarded on behalf of all animals that served in WWI.

Only one cat ever received the award for bravery: "or keeping the crew's morale up and the rats down." Simon was smuggled aboard the HMS Amethyst of the Royal Navy by a 17-year-old seaman who found the malnourished kitty wandering the dockyards of Hong Kong. The black-and-white cat soon became a favorite onboard, protecting their food from a rat infestation and snuggling up to the crew. Bob survived injuries from a cannon shell but sadly died in quarantine shortly after returning home.
