I suppose if we are being specific, like in the War of the Roses. were men organized like units with some sort of officer leading them? or was it much more disorganized?
This question might be of interest to you.
I answered a similar question a while back. The time period is a touch earlier than your question (10th and 11th centuries) but the points are still relevant.
A short summary would be, yes medieval soldiers in organized professional armies (the Roman Byzantines are my example) generally fought in units. However, the units could be made up of many types of soldiers with different roles and equipment, unlike games like Total war where units are homogenous.
