What are field of operations?

Famous quotes containing the words operations and/or field:

    Plot, rules, nor even poetry, are not half so great beauties in tragedy or comedy as a just imitation of nature, of character, of the passions and their operations in diversified situations.

    Vigil strange I kept on the field one night;
    When you my son and my comrade dropt at my side that day,
    One look I but gave which your dear eyes return’d with a look I
    shall never forget,
    One touch of your hand to mine O boy, reach’d up as you lay on the ground,
    Walt Whitman (1819–1892)
