army, force, troops, war, battle
軍 centers on organized military force: an army, troops, or the collective effort of war and battle.
軍 combines 冖 (cover) and 車 (chariot), originally depicting a covered war chariot, which came to represent the army or military force.
A covered 冖 war chariot 車 is the core of an ancient army. Picture rows of covered chariots rolling into battle.
For グン, imagine a gun being fired from a covered chariot: gun -> グン, and the chariot is part of the army.
