solider

Solider is a common misspelling of soldier. The standard term 'soldier' refers to a person who serves in an army or other armed forces, typically as a combatant or support specialist. Soldiers may be deployed in national defense, peacekeeping, disaster response, or humanitarian missions, and they operate under military law and command structures.

Roles and specialties vary: infantry, armored units, artillery, engineers, signals, logistics, medical services, and special forces. While some soldiers are frontline combatants, many serve in support functions that sustain mobility, supply lines, and communications. Training emphasizes physical fitness, weapons handling, drill, marksmanship, tactics, first aid, and rules of engagement. Recruits usually undergo basic training before advancing to their chosen specialty.

Historically, soldiers have existed since ancient organized warfare and have evolved from citizen-soldiers and mercenaries to professional standing armies. In many nations, conscription coexists with voluntary service; in others, service is voluntary. Today's soldiers operate within international law and the codes governing armed conflict, including the protection of civilians and treatment of prisoners of war. The term 'solider' is widely regarded as a misspelling of 'soldier.'
