What are the similarities between the military reforms of Karl Martell and Alfred the Great?

Karl Martell and Alfred the Great embarked on the path of abandoning the military militia and forming a military class. The landowners who were freed from work on the ground became the basis of the army of the new type. They had to devote all their time to improving military skills. The care for the maintenance of such an army completely fell on the peasants and ordinary people, thereby not burdening the treasury of the rulers. Depending on the income of the lands, each separate region had to provide a certain number of warriors.
