I want to know the answer to the following question:
vytautas created what for compromising professional warriors?
All the background I'm provided with is that "As there were not enough nobles, Vytautas trained suitable men, relieving them of labor on the land and of other duties; for their military service to the Grand Duke, they were granted land that was worked by hired men (veldams).". Is that enough to answer the question?
Answer: no
