Yes. Service members do not surrender the Constitution when they put on the uniform, and constitutional arguments are a routine, important part of court-martial defense. The key is understanding a nuance: most constitutional protections apply in the military, a few apply differently, and one notable right does not apply at all. Knowing which is which is what makes the argument work.
The general rule, and one big exception
The governing principle is broad: service members are entitled to constitutional rights except those that, expressly or by implication, do not apply to the military. Most protections carry over.
The most prominent thing that does not carry over is the Fifth Amendment right to grand-jury indictment. The Constitution’s grand-jury requirement expressly excepts cases arising in the armed forces, which is why serious charges go through an Article 32 preliminary hearing rather than a civilian grand jury. Recognizing that distinction keeps a defense from arguing for a protection that simply does not exist here.
Protections that apply, sometimes more strongly
Several core constitutional protections are fully live in a court-martial, and one is arguably stronger than in civilian life:
- Self-incrimination. The Fifth Amendment privilege applies, and the military adds Article 31(b) warnings, which are broader than civilian Miranda warnings and required before official questioning of a suspect. The privilege is guarded especially closely given the coercive pressures of a military environment.
- Unreasonable search and seizure. Fourth Amendment principles apply through the Military Rules of Evidence, which govern searches, seizures, and the suppression of unlawfully obtained evidence.
- Due process and a fair trial. These protections run throughout the proceeding.
How a violation becomes an argument
The practical vehicle is exclusion: a statement taken in violation of the privilege against self-incrimination or Article 31, or evidence from an unlawful search, can be challenged and kept out. So the defense identifies the right, shows the violation, and asks the court to suppress the tainted evidence or otherwise remedy the breach.
Imagine a member who expects a grand jury and is surprised by an Article 32 hearing instead: the attorney explains which constitutional protections carry into the court-martial and which, like the grand-jury right, do not.
The key point is that constitutional litigation is fully available in courts-martial, with one map worth memorizing: nearly all protections apply, self-incrimination comes with the extra Article 31 layer, search-and-seizure runs through the Military Rules of Evidence, and the grand-jury right is replaced by the Article 32 hearing. Arguing the right protection, in the right vehicle, is the whole craft.
