what is the difference between a pen knife and a pocket knife
Penknife Today the word penknife is the common British English term for both a pocketknife, which can have single or multiple blades, and for multi-tools, with additional tools incorporated into the design.[2]
Marksman The main difference between military marksmen and snipers is that marksmen are usually considered an organic part of a fireteam of soldiers and are never expected to operate independently, whereas snipers usually work alone or in very small teams with independent mission objectives. Snipers are also often tasked with responsibilities other than delivering long-range fire â€” specifically, conducting reconnaissance and directing coordinates for artillery fire or air strikes. Within the military, marksmen are sometimes attached to an infantry fireteam or squad (where they are known as designated marksmen) where they support the squad by providing accurate long-range shots at valuable targets as needed, thus extending the effective tactical reach of the fireteam or squad.
