The observation of an objective from an observation post (OP)
A long-range observation is a type of observation conducted over an extended period of time or distance, often used in fields such as astronomy, meteorology, or environmental monitoring. This type of observation allows for the tracking and analysis of trends, patterns, or changes that occur over a long period.
Long-range and short-range observation and surveillance.
A theory unites and explains a range of observations.
A short range observation refers to gathering data or information from a close distance, typically within a limited range or proximity to the subject being observed. This type of observation is often used in fields such as wildlife research, surveillance, or security monitoring where detailed and immediate data is needed.

Long-range artillery with rifled barrels. The telegraph. Moving troops by rail. Observation balloons. Submarines.
Because it's a numerical observation
Depends on the subject. Could range from scientific observation to surveys.
You treat each observation in a particular range as if it were the middle value of that range.

The range is the difference between the maximum and minimum observation in a set of data. Thus the range is 12 (23 - 11).
