instruction: How many total men fought at Kosovo Field according to text?
context: The Crusaders, numbering 22,000-30,000 arrived at Kosovo Field (the site of the first Battle of Kosovo in 1389, between Serbs and Ottomans) having faced an Ottoman army of 40,000-60,000 men Sultan Murad personally commanded a large section of cannons and janissaries, while his son and would-be successor, 16-year-old Mehmed, who faced battle for the first time, led the Anatolian troops at the right wing. Hunyadi commanded the center of his army in the battle, while the Crusaders right wing was under the Wallachians. The Hungarians had long barrage cannons. Calculating that he would need more than 40,000 men to defeat the Ottomans, the Hungarian regent sought to join up with anti-Ottoman Albanian forces, possibly led by Skanderbeg. The Ottomans in their base at Sofia received word of the Crusader army's march route and subsequently began readying their men.
response: The Crusaders fielded 22,000-30,000 men and the Ottomans 40,000-60,000 for a combined total of 62,000-90,000 men.
