A primary tactic used by the Union Army during the Battle of Gettysburg was Defensive positioning.

Union General George Meade fortified key defensive positions on elevated terrain, notably at Cemetery Hill, Cemetery Ridge, and Little Round Top. This strategy was designed to take advantage of the landscape, enabling Union forces to withstand Confederate assaults more efficiently. By maintaining these defensive lines, the Union was able to safeguard their flanks and establish a strong barrier against the advancing Confederate forces, which played a crucial role in their victory in the battle.
