BCGs in Marine Corps terms refer to what protective eyewear?

• A. Birth control glasses - basic combat glasses
• B. Ballistic combat goggles
• C. Binoculars
• D. Bronze corrective glasses

Answer: (A)

BCGs refer to protective eyewear worn in Marine Corps settings, specifically basic combat glasses. Marines often use the nickname “birth control glasses” for these, reflecting the humor around their protective purpose. The idea is simple: these glasses are designed to shield eyes from debris, wind, dust, and minor hazards during training and in the field, helping maintain vision and readiness.

They are lighter and less bulky than ballistic goggles, which are built for higher-velocity threats and typically seal around the eyes for greater protection. Binoculars are unrelated, as they’re viewing optics, and bronze corrective glasses are just regular prescription eyewear without the combat protection function. So, the term that matches the protective eyewear described is the basic combat glasses, commonly referred to as birth control glasses.
