For "Elite soldier of ancient Persia", I came up with "Cataphract" and then wasted several minutes trying to figure out how I was screwing up the spelling. Maybe make the clue more specific, like "Elite foot-soldier"?
The musketeers were trained in using muskets and swords, pikes, or daggers. Firearms of the age were slow to reload and not very accurate meaning that in a battle that started as a fire fight it might end up as a melee. Common musketeers were probably not very adept at using bladed weapons, as the musket was a way of making even a minimally trained soldier deadly, but the three musketeers in the Dumas novel are not just musketeers but part of the king's elite guard. Once the rifle replaced the musket and the bayonet was invented and popularized, use of swords by foot soldiers gradually died out, though cavalry continued to use sabers for almost another three centuries. The musketeers of France included both foot soldiers and light cavalry, the light cavalry were called dragoons.
I am from New England and minute men are a pretty big deal, since they fought most of the revolution in the year of our lord 1775, including actions at Lexington, Concord, and Bunker Hill. Until congress formally created the continental army they relied on militia who could be prepared at a minutes notice
Could you consider accepting "mounted infantry" for "mounted soldier who dismounts to fight on foot" (used extensively in Anglo-Boer War)? Either that or specify a time period for this question. Great quiz, thanks.
Hard to understand the spelling accuracy requried in these quizzes. Centurian gets refused as a spelling of Centurion but Ghurka is accepted for Gurkha. Strange.
Hate to be "that guy," but the irregular soldier should technically be guerillero. Guerilla means "little war" and is a term for that style of combat, but the individual soldier in it is guerillero.
Please consider "sellsword" for "mercenary." Obviously mercenary is the better answer, but i've been watching a lot of game of thrones recently and it came to mind first and still matches the clue. :-)
In the UK, the parachute regiment is known as the Paras, an individual member is a Para. Please either accept as an answer or specify that you're being US-centric. Again...
