Tunder S14

"This assault rifle combined with a grenade launcher, which is similar to the AKM series, was specifically developed for rapid response units. The main differences are its 9x39 caliber ammunition, bullpup layout and extensive configuration options. This weapon is highly valued by military stalkers due to its ability to kill enemies wearing body armor behind improvised cover at a distance during urban combat, as well as its excellent stopping power."
