First thing first, these as for now are the Pinnath Gelin cavalry, upgraded and not.
Main topic now. My intention is to rethink Gondor's fiefdoms military, building it up similarly to the italian city-states (Tolkien's historical source of ispiration). For this reason, I picked an italian medieval state for each fiefdom, and I'm taking their military as a reference.
*WARNING* historical rant ahead
Pinnath Gelin
Pinnath Gelin's counterpart is Florence. Both of them are fertile and hilly lands; moreover Hirluin arrived into Minas Tirith with "three hundred of gallant green-clad men", and Florence was one of the main cloth producers at the time.
So, I took the depictions of the battle of Campaldino, a battle between Florence and Arezzo on 1289
Cavalry is the main fighting force, and it's composed by the lords and their retinues, both well trained and equipped.
Infantrymen are equipped with a spear and a big recttangular shields, the pavise, with which they form literally a wall. An Aretine poet wrote that the archbishop Guglielmino degli Ubertini, Arezzo's commander, was actually shortsighted, and when he looked at the battlefield, where the florentine infantry formation already standed , he asked his aides what city's were the walls in the plain.
For these reasons, I'm thinking about something like this
