The terms "soft target" and "hard target" are flexible in nature and the distinction between the two is not always clear. However, typical "soft targets" are civilian sites where unarmed people congregate in large numbers; examples include
national monuments, hospitals, schools, sporting arenas, hotels, cultural centers, movie theaters,
cafés and restaurants,
places of worship,
nightclubs, shopping centers, transportation sites (such as
railway stations,
buses,
rail systems, and ferries), and farmers' cooperatives. Soft targets are contrasted with hard targets, which are well-protected. Examples of hard targets include airports, government buildings, military installations,
diplomatic missions, and
power stations. Hard targets have
access controls that prevent public access. ==History==
