Disciplined/disciplinary

Disciplined/disciplinary
 

-Immigration officers have fewer dangerous duties than people in other disciplined forces.
-Immigration officers have fewer dangerous duties than people in other disciplinary forces.

Are they just the same thing?

These sentences do not mean the same thing.

1. But are they both correct?
2. What's the difference?

disciplined=have to listen to orders from above
disciplinary=related to discipline

Both sentences are correct, but do not mean the same thing.

disciplined = behavior in accord with rules of conduct; behavior and order maintained by training and command; rigorous

disciplinary = enforcing or administrating discipline

The former describes the behavior or characteristic of a group. The latter describes a directive or function of a group.

Thank you.

Grammatically both sentences are correct. However, and this may be a cultural thing, to call immigration officers members of a "disciplinary force" sounds wrong to me. The term is clearly appropriate for prison officers, and seems reasonable to apply to police officers who have the power to issue formal cautions and/or small fines and, maybe, magistrates, but I can't think of any other institution for which it seems suitable.

What's Inglés?

Inglés is English in the Spanish language.
Constabulary may be a better term than disciplinary.

Thank you.
