What are the markings on HE mortar rounds?

The markings on high-explosive (HE) mortar rounds are specifically olive drab with yellow markings. This color scheme is part of the standardized system used by military forces to quickly and easily identify the type of ammunition. Olive drab is a common color for military ordnance as it provides a neutral background suitable for camouflage. The yellow markings indicate that the round is explosive in nature, which is critical for ensuring that personnel handling the ammunition can recognize its potential hazards and characteristics at a glance. This color-coding system helps maintain safety during storage, transport, and use, reflecting established military protocols for munitions.
