Final answer:
A position area for artillery (PAA) is where artillery systems can move to increase their survivability, a concept pertinent to military operations and essential in World War I artillery tactics.
Step-by-step explanation:
A position area for artillery (PAA) is an area assigned to an artillery unit where individual artillery systems can maneuver to increase their survivability.
This term is closely associated with military operations and particularly with World War I, where artillery played a crucial role.
The use of long-range artillery was essential for armies, as it was often placed behind the trench systems that spanned nearly five hundred miles at the front.
The artillery units would provide barrage fire to "soften" enemy forces before infantry troops advanced over the top into no-man's land, facing machine gun fire if the artillery had not been effective enough.
Manoeuvring around the side of an army, rather than attacking directly from the front, is a tactic called flanking, which can force an enemy into narrow passes or target their weaker sides, essentially trying to gain a tactical advantage through indirect maneuvers.
