Lines: 28 Approved: military@amd.com From: henry@zoo.toronto.edu Mail from *another* Field Artillery type who can't post directly, Tim Duggan : ------------- Strictly speaking, High Angle is the range of elevations in which an increase in elevation will cause a corresponding decrease in range. In a perfect world, this would always occur at 800(!) mils or 45 degrees. Hi angle usually occurs fairly close to 800 mils - most firing tables also contain entries in this range - the Probable Error in Range is listed alongside so that the observer and FDO can judge for themselves what is unacceptable. a GUN is a direct fire weapon a HOWITZER is a direct and indirect fire weapon that fires both low and high angle a MORTAR is an indirect fire weapon that fires high angle only The above definitions are perfect for explaining the differences between the cannons on tanks, artillery, and anti-aircraft weapons... if only all of my peers would stop referring to howitzers as guns! :-) - Tim Duggan
