What is the CBRN motto?

• A. Proelium Elementis Regamus
• B. Elementis Regamus Bellum
• C. Elementis Regamus Opera
• D. Elementis Regamus Proelium

Answer: (D)

In a Latin motto for a CBRN unit, you want a concise, battle-focused phrase that communicates mastery of the elements in combat. The option that places Proelium at the end delivers a sharp, action-oriented punch: Elementis Regamus Proelium translates roughly to “We master the elements in battle” or “We rule the battle with the elements.” The phrase Elementis Regamus is common across the choices, signaling command of the elemental domain, and ending with Proelium gives the motto a strong, battlefield-specific sense.

Using Bellum would shift the sense to war in a more general sense, which feels less immediate for a motto. Opera means works or deeds, which doesn’t fit the idea of mastering elemental forces in combat. So the combination that stays tight, combat-focused and idiomatic as a motto is the one with Proelium at the end.
