Introduction
Military defense evidence begins to take shape as soon as an independent military defense investigator is retained and starts identifying, preserving, and developing the facts that may strengthen the defense.
They often imagine a single interview or a quick review of documents, when in reality a professional defense investigation is a structured, methodical process that develops over time. It begins by identifying the most important factual issues, determining what evidence is at risk of being lost, and establishing investigative priorities with defense counsel. As witnesses are interviewed, documents are reviewed, digital evidence is preserved, and new information is uncovered, the investigation continues to evolve. Every step is guided by one objective: developing reliable, objective facts that help the defense make informed legal decisions—not proving a predetermined theory.
A successful investigation is built on careful planning, thorough fact development, and close communication between the investigator, the client, and defense counsel.
