Armor is protective equipment worn by Guardians to deflect damage and prevent injury. In game, armor is divided between multiple slots that correspond to a different body part, and can have unlockable upgrades that can provide further benefits during combat, especially with rarer pieces. Armor pieces that offer more protection also tend to be rarer. 
Patrol is an activity available in Destiny .  Patrol allows players to freely roam in a location . Players can battle enemies , locate and accept patrol missions, partake in Public Events , or simply explore at their own leisure.
