Frequently asked questions

What is the base offense level for losing national defense information?

The guideline for losing national defense information is §2M3.4 of the federal Sentencing Guidelines. Before any adjustments, its starting level depends on the facts: from level 13 to level 18. The table on this page lists each starting point.

Using the first starting point in the table on this page (level 13) alone, a person with no criminal history points who pleads guilty scores 4–10 months, including the 2-level zero-point reduction. Adjustments such as role in the offense or obstruction can change the level, and the judge can sentence outside the range.

Is probation possible for losing national defense information?

Possibly, with conditions. At the first starting point in the table with a guilty plea and the zero-point reduction the range is in Zone B, which allows probation with home detention, community confinement or intermittent confinement, unless the offense is a Class A or B felony or the statute rules probation out (§5B1.1(b)).
