Whether you’re a sniper, spotter, or infantry leader preparing for qualification or deployment, understanding this form ensures accurate target engagement in any environment.
This 2026-updated guide covers everything you need: what DA Form 7637 is, why it matters, how to fill it out correctly, and where to download the latest fillable PDF directly from Army Publishing Directorate (armypubs.army.mil).
What Is DA Form 7637? Official Sniper’s Range Card Explained
DA Form 7637 (dated December 2017) is the standardized Sniper’s Range Card used by U.S. Army snipers. It replaces the obsolete DA Form 5786-R and is prescribed by TC 3-22.10 (Sniper), with TRADOC as the proponent agency. Previous editions are obsolete.
Unlike general range cards (such as DA Form 5517-R used for crew-served weapons), the sniper-specific version focuses on ballistic data tailored to long-range precision rifles. It captures:
- Firing position details
- Target ranges
- Elevation and windage corrections
- Wind conditions
- Target Reference Points (TRPs)
Snipers complete one card per firing position or sector of fire. The completed form becomes a quick-reference tool during operations, training, or live-fire exercises.
Why Every U.S. Army Sniper Needs a Range Card?
In sniper operations, seconds count and environmental factors (range, wind, elevation) change constantly. A properly prepared Sniper’s Range Card (DA Form 7637) delivers:
- Faster target acquisition — Pre-recorded data eliminates guesswork.
- Improved first-round hit probability — Precise elevation and windage values account for bullet drop and drift.
- Better situational awareness — TRPs and azimuths help orient the team quickly.
- Standardized documentation — Essential for range safety, after-action reviews, and qualification under TC 3-22.10 standards.
Units across the Army — from light infantry to Special Forces — use this form during sniper school, unit training, and real-world missions.
Complete Breakdown of DA Form 7637 Fields
The form is a single-page, easy-to-use template with dedicated sections for critical data:
| Section | Purpose | Key Fields / Data to Record |
|---|---|---|
| Position Identification | Identifies the sniper team’s exact location | Grid coordinates, description of hide/position |
| Range | Distance to each target or reference point | Meters (or yards, per unit SOP) |
| Elevation | Vertical scope adjustment (clicks or mils) | Scope elevation setting |
| Windage | Horizontal scope adjustment for wind drift | Scope windage setting |
| Wind | Environmental wind data for the shot | High/Low velocity, direction, azimuth |
| TRP (Target Reference Points) | Up to 3 pre-designated reference points for quick orientation | TRP 1–3: Azimuth and Distance |
| Method of Obtaining Range | How the distance was measured (critical for verification) | Laser rangefinder, map, GPS, etc. |
| Description | Additional notes, observations, or sketch space | Terrain features, obstacles, remarks |
Note: The form also includes a TEMP field in some layouts for temperature (which affects ballistic calculations).
Step-by-Step: How to Fill Out DA Form 7637?
- Start with Position Identification — Record your exact firing position (e.g., grid coordinate, hide description).
- Determine Ranges — Use a laser rangefinder or map reconnaissance to measure distances to key targets and TRPs.
- Calculate Ballistics — Input elevation and windage adjustments based on your rifle’s dope (data on personal equipment) and current conditions.
- Record Wind Data — Note high/low wind velocity, direction, and azimuth. Update as conditions change.
- Plot TRPs — Select up to three prominent terrain features. Record azimuth and distance to each.
- Document Method & Notes — Write how you obtained the range and any additional details (e.g., “Laser confirmed at 0830 hrs”).
- Review & Update — Range cards are living documents. Re-verify data whenever conditions (light, wind, temperature) change significantly.
Pro tip: Fill the card in the field using a pencil or waterproof pen. Many units laminate completed cards for durability.
Best Practices and Common Mistakes to Avoid
Best Practices:
- Create a card for every firing position and sector.
- Cross-reference with your rifle’s ballistic calculator or Kestrel.
- Train your spotter to read and update the card quickly.
- Integrate with military sketches (DA Form 7638) for full situational awareness.
Common Mistakes:
- Relying on outdated wind or temperature data.
- Skipping the “Method of Obtaining Range” field.
- Using the wrong form (ensure it’s the current DEC 2017 version of DA Form 7637).
