Some soldiers would fight with melee weapons (sword, axe, spear, pike etc) and others would be armed with missile weapons (musket bow, longbow, crossbow, sling etc). These weapons varied depending on time period and culture.
Soldiers in Re-Enactment
In general, many of the people who do combat re-enactments will portray soldiers. Whilst a strict ratio is uncommon in some groups, others deliberately limit the amount of people portraying units above the general rank and file.
