I don’t know what a parapet is used for or a Barbed wit and fire step

A parapet is a protective wall or earth defense along the top of a trench or other place of concealment for troops. And a barbed wire is wire with clusters of short, sharp spikes set at intervals along it, used to make fences or in warfare as an obstruction. Parapets were originally used to defend buildings from military attack. Barbed wire went from being largely defensive to working as a deadly instrument in World War I. On the front, soldiers laid out wire to defend their trenches.

The United States has 120.5 guns per 100 people, or about 393,347,000 guns, which is the highest total and per capita number in the world. 22% of Americans own one or more guns (35% of men and 12% of women). America’s pervasive gun culture stems in part from its colonial history, revolutionary roots, frontier expansion, and the Second Amendment, which states: “A well regulated militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.” Proponents of more gun control laws state that the Second Amendment was intended for militias; that gun violence would be reduced; that gun restrictions have always existed; and that a majority of Americans, including gun owners, support new gun restrictions.
