You watched as what looked like a group of soldiers wearing combat helmets with night vision goggles attached, snow goggles, military-grade respirators/oxygen tanks, black tactical winter clothing, and body armor made their way up the mountain. You also noticed that the men were carrying Colt M4A1 carbines (A gas-operated assault rifle that uses a 30-round STANAG magazine loaded with 5.56×45mm NATO ammunition).
