Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'ядерная боеголовка' – it's a direct and correct translation. The trap is in the phrase 'nuclear weapon' (ядерное оружие), which is a broader category.
Common Mistakes
- Pronouncing 'nuclear' as 'nuc-u-lar' (non-standard). Using 'warhead' to refer to the entire missile. Confusing 'warhead' with 'payload', which can be non-explosive.
