    There are quite a few different methods of judging distances without using laser range finders or surveying equipment. Most of these method have been developed by the military and others in the field.

    Several, are outlined in a Marine Corps field training lesson plan on range estimation, and it can be found as a Word .doc at:

    www.lejeune.marines.mil/.../27/.../CMC-30%20Range%20Estimation.doc

    other methods such as using flash-bang (or crack-thump of small arms), and using telescopic and binocular graticules (using the subtention rule...i.e. 1mil =-1metre at 1,000 metres) are explained at:

    Estimate Range (ArmyStudyGuide.com).

    If some of the distance and angle values are known, then pythagoras' theorem can be used to calculate the unknown values
