Translation Traps (for Russian speakers)
- Do not translate as simply 'офицер' (officer) or 'охрана' (guard). The phrase is a title for a specific duty. A closer equivalent is 'начальник караула' or 'дежурный офицер караула'.
- Avoid using 'офицер охраны', which sounds more like a security firm employee.
Common Mistakes
- Using 'officer of the guard' to mean any military police officer or security guard. It is a specific temporary duty post.
- Omitting the definite article 'the' (i.e., saying 'officer of guard').
- Confusing it with 'officer of the watch' (nautical).
