Just to save space, I won't "quote" last piece, but will refer
to addressee's "callsign", hope this is OK with "CX".
Apologies for delay response, but "Shotgun"s post clarify my
position quite well.
Information of the Upper Echelon's general intent or work plan,
will help any lower echelon COMMANDER to ensure that accidents do
not happen, both in attack or defensive mode.
There will be instances where an attack may meet up with a strong
counter attack from opposing force(s), and the Attacking Force may
have to switch to defensive role, calling in support (arty, air,
armor or infantry) from any available neighboring forces.
The movie "We are Soldiers" was a clear depiction of real life
event during the Vietnam War, when air and arty support was called
in right into their grid square, as the single US battalion was
being overwhelmed by a superior Vietnamese Force.
In a Battalion attack or defense, a Section Commander can benefit
if he understand the general direction or intention for his
Battalion, and if need be up to Brigade Level (that covers several
map grids).
If ever the section get lost, it will not be detrimental if the
Section Commander and his men has a fair knowledge as to which
direction to move, to meet up with friendly forces (or not to move,
in the event of walking into friendly fire or killing zones, or
lines of attack).
Information on call, will certainly help in modern warfare, where
events can move or change very rapidly.
