Assaulting or Impeding a Federal Officer Sentence Calculator

Starting level and typical ranges

These ranges use the starting level alone, before any of the facts listed below, for someone with no criminal record unless the column says otherwise. Most real cases add levels.

Starting point	Level	Trial	Guilty plea	Plea + zero-point	Category IV, plea
Obstructing or impeding officers, the starting point	10	6–12 months	0–6 months	n/a	10–16 months

The 2-level zero-point reduction is generally not available for this kind of offense, because it usually involves violence, a credible threat or a weapon (§4C1.1(a)(3), (a)(7)).

What changes the sentence

Each of these facts moves the offense level under §2A2.4. Adjustments that apply to every offense, such as role in the offense, obstruction, a guilty plea and criminal history, come after these.

Fact	Effect	Rule
Was there physical contact, or a dangerous weapon whose use was threatened: Yes, physical contact, or a weapon was possessed and its use was threatened	+3	§2A2.4(b)(1)
Did the victim suffer bodily injury: Yes	+2	§2A2.4(b)(2)

Important details

If the conduct was an aggravated assault, the aggravated assault guideline applies instead (§2A2.4(c)(1)).
The starting level already accounts for the victim being a government officer performing official duties, so the official victim adjustment (§3A1.2) is not added here, unless the aggravated assault guideline applies through the cross reference (§2A2.4, note 2).
If the person created a substantial risk of death or serious bodily injury to another person while fleeing from law enforcement, and no higher adjustment covers that conduct, the reckless endangerment adjustment (§3C1.2) applies (§2A2.4, note 2).
The calculator does not apply mandatory minimum sentences set by statute for this offense. If the statute of conviction requires one and it is higher than the range shown, the minimum controls; check the statute or ask a lawyer.

Frequently asked questions

What is the base offense level for assaulting or impeding a federal officer?

The guideline for assaulting or impeding a federal officer is §2A2.4 of the federal Sentencing Guidelines. Its starting level is 10, before any adjustments.

What is the guideline range for assaulting or impeding a federal officer with no criminal history points and a guilty plea?

Using the starting level alone, a person with no criminal history points who pleads guilty scores 0–6 months. The facts listed under “What changes the sentence” can add levels, and the judge can sentence outside the range.

Is probation possible for assaulting or impeding a federal officer?

The guidelines allow it at the starting level: with a guilty plea the range begins at 0 months (Zone A), so prison is not required, unless the offense is a Class A or B felony or the statute rules probation out (§5B1.1(b)). Added facts can raise the range out of Zone A.

Is the calculator accurate for assaulting or impeding a federal officer?

It follows §2A2.4 of the Guidelines Manual effective November 1, 2025. It passed 5 review rounds, each comparing every number, rule and label with the manual text, and its last round found nothing to correct. Those reviews were done with AI tools, not by lawyers, and it has not yet been reviewed by an attorney, so mistakes are possible. The guidelines are advisory, and a lawyer who knows the case can tell you what actually applies.
