For some examples it would be things such as tanker or artilleryman or craftsman or medic.
Most of the time it is my the occupation such as paratrooper, grenadier, ranger, sniper, engineer, sapper, craftsman,  just to name a few
My brother is a soldier and i really think he is extremly brave. I see, so they're a part of an army. Yes, but  it's a very dangerous task i think soldiers really are people that love their country I can't speak about that but did you know the word "soldier" comes from a Middle English word, "soudeour"? that is so interesting i would have never imagined could you tell me more about the history of soldiers? Well "soldier" is more of a general meaning as the military occupations are becoming more specialized. Wow, interesting do you know any soldiers? None, but continuing from before, the soldier is referred to instead with a rank or name that reflects them in some way such as a specialty arm or military branch. Oh, i didn't know that what are some of the ranks you mention
As a result, ''soldiers'' are referred to by names or ranks which reflect an individual's military occupation specialty arm, service, or branch of military employment, their type of unit, or operational employment or technical use such as: trooper, tanker (a member of tank crew), commando, dragoon, infantryman, artilleryman, marine, paratrooper, grenadier, ranger, sniper, engineer, sapper, craftsman, signaller, medic, or a gunner.
