I spent few hours to search the ancient Greek literature for a quote that will connect the term HOPLON with the SHIELD.
I knew that once I present the quotation from the ancient Greek text and the translation in English from the Tufts (USA) university, even a Greek would understand that the shield of the Hoplite is called HOPLON.

[2] Of the votive offerings in the temple these are the most notable. There is the hide of the Calydonian boar, rotted by age and by now altogether without bristles. Hanging up are the fetters, except such as have been destroyed by rust, worn by the Lacedaemonian prisoners when they dug the plain of Tegea. There have been dedicated a sacred couch of Athena, a portrait painting of Auge, and the shield of Marpessa, surnamed Choera, a woman of Tegea;

Ok, Gentlemen... I think here ends this issue...

I may have been accused of being arrogant but at least I am not ignorant... and the ancient Greeks called the hoplite shield with the term: HOPLON (according to Pausanias)
Another small detail that needs to be clarified...
Yianitsaros is the Greek term for Yanissaries
Definition of Yanissaries:
Janissaries (jăn'ĭs??r'ēz) [Turk.,=recruits], elite corps in the service of the Ottoman Empire (Turkey). It was composed of war captives and Christian youths pressed into service; all the recruits were converted to Islam and trained under the strictest discipline. It was originally organized by Sultan Murad I. The Janissaries gained great power in the Ottoman Empire and made and unmade sultans. By 1600, Muslims had begun to enter the corps, largely through bribery, and in the 17th cent. membership in the corps became largely hereditary, while the drafting of Christians gradually ceased. In 1826, Sultan Mahmud II rid himself of the unruly (and by now inefficient) Janissaries by having them massacred in their barracks by his loyal Spahis.
