The Ottoman Empire was seen as the "Sick man of Europe" after decades of slow decline. The empire wasn't out yet and when the British and French came to knock them out the war. The Ottomans fought back.
Junior Officers were the cornerstone of the Ottoman force's command structure.
Equipped with a MG09. They could throw a lot of lead down range.
Conscription's age was lowered just before the wars start, from 20 years old to 18 years old.
The Ottoman Empire had plenty of Arabs fighting for them. In fact, one third of Ottoman Forces were Arabs. More than on the Arab Revolt.
Like all armies, their non-commissioned officers are leading troops, and advising the officers.
