What is similar in the military reforms of Charles Martell in the French state?

One can distinguish such similarities in the reforms of Karl Martel, Henry 1 and Alfred the Great:
1) The rulers abandoned the creation of a militia and began to build a military estate;
2) Landowners were able to become a privileged military class, which was exempted from land work.
Such decisions were made by the kings for the reason that a reformation of the army was needed, which was to become a powerful force and support for the monarch.
