In Animal Farm, what are the two animal military decorations?
After the farmers attempt to retake the Animal Farm, the victorious animals create two military medals, "Animal Hero, First Class," and "Animal Hero, Second Class." Snowball and Boxer receive the first for their efforts in routing the humans, while a sheep killed in action receives the second. However, when Snowball is expelled from the farm, the medals become a tool of propaganda instead of a genuine honor. Napoleon promises a medal and apples to any animal who can bring Snowball in. Later, he adopts both medals himself:
Napoleon emerged from the farmhouse, wearing both his medals (for he had recently awarded himself 'Animal Hero, First Class,' and 'Animal Hero, Second Class'), with his nine huge dogs frisking round him and uttering growls that sent shivers down all the animals' spines.

This is standard behavior for dictators, who often never serve in a military capacity but still promote themselves to General and appear in public with many distinguished medals. By giving himself the medals, which are remembered for their original meaning by the animals, Napoleon takes on a history of courage and responsibility that he has not earned, and also keeps any other animal from seeking to earn higher honors than himself.
Following The Battle of the Cowshed in chapter 4, the animals unanimously create two military decorations, which are titled "Animal Hero, First Class" and "Animal Hero, Second Class." Snowball and Boxer are both recipients of the military decoration "Animal Hero, First Class" and are awarded brass medals for their extraordinary courage and valor during The Battle of the Cowshed. The military decoration "Animal Hero, Second Class" is posthumously awarded to a sheep that lost its life during the battle.
Later on in the novella, Napoleon usurps power and expels Snowball, claiming that he is a traitor. In chapter 7. Napoleon claims that Snowball attempted to thwart their effort to build the windmill and offers any animal the decoration "Animal Hero, Second Class" along with a bushel of apples to whoever brings Snowball to justice. Squealer then tells the animals that Snowball fought on Jones's side during The Battle of the Cowshed and says that they mistakenly awarded Snowball the medal. Towards the end of chapter 7, Napoleon emerges from the farmhouse wearing both military decorations. While Napoleon never earned those military decorations, they add to his striking image, which gives him the illusion of courage and authority.
