M-Tac Helm of Terror Laser Cut patch featuring ægishjálmur (the Helm of Terror).

The Helm of Terror is an Icelandic magical sign based on runic writing, used as protection against the use of force, causing a sense of fear in the enemy. ægishjálmur is a sigil that was popular in the early Middle Ages, mainly among the Vikings and northern peoples inhabiting the territory of modern-day Iceland. It belongs to the "helms of terror” - signs designed to strike fear into enemies and make them flee. Nothing surprising, because the history of nations, and especially the history of the Vikings, is mainly the history of wars of liberation and invasion, in which the main goal was always victory over the enemy.
