DA Form 7660-R: HBCT Gunnery Table I Platoon Roll-Up

DA Form 7660-R: HBCT Gunnery Table I Platoon Roll-Up – U.S. Army soldiers and leaders in Heavy Brigade Combat Teams (HBCT) rely on standardized tools to maintain combat readiness. DA Form 7660-R serves as a key document for recording and summarizing platoon-level results from Gunnery Table I: Crew Critical Skills Test. This form helps units track crew proficiency in essential vehicle and weapon system tasks before advancing to live-fire exercises.

What Is DA Form 7660-R?

DA Form 7660-R (SEP 2009) is titled HBCT GUNNERY TABLE I – CREW CRITICAL SKILLS TEST PLATOON ROLL-UP. The U.S. Army publishes it for use with FM 3-20.21 (Heavy Brigade Combat Team (HBCT) Gunnery), with TRADOC as the proponent agency.

This one-page form aggregates individual and crew performance data from the Crew Critical Skills Test (part of prerequisite training). It provides a platoon-level overview of Go/No-Go results across various platforms and tasks. Commanders, Master Gunners, and platoon leaders use it to identify strengths, gaps, and overall readiness.

Purpose of Gunnery Table I and the Crew Critical Skills Test

Gunnery Table I evaluates crews on critical skills needed for safe and effective operations of armored and support vehicles. It tests the entire crew’s ability to perform time-sensitive tasks as a team, rather than individual marksmanship.

This table acts as a foundational prerequisite (often paired with the Gunnery Skills Test or GST) before crews proceed to simulations (Table II), basic gunnery, or qualification tables. High first-time Go rates indicate strong individual and collective training. Low rates signal the need for remedial training in the motor pool or with simulators.

Key Tasks Covered on DA Form 7660-R

The form organizes tasks by vehicle/platform type, including:

  • Common Tasks (applicable across platforms)
  • Abrams Tasks (M1 series tanks)
  • Bradley Tasks (M2/M3 Fighting Vehicles)
  • Guardian Tasks (e.g., M1117 Armored Security Vehicle)
  • Truck Tasks (armed HMMWVs and similar)

Example Critical Tasks (from the form layout):

  • Boresight procedures
  • Misfire drills (25mm, TOW, etc.)
  • Remove M242 chain gun / breechblock procedures
  • Mount M48 and MK19
  • Send/Receive radio and digital reports
  • Evacuate crewman (multiple scenarios)
  • Rollover drill
  • Fire evac drill

Evaluators score each crew member (VC, GNR, DVR, LDR) on specific subtasks with Go/No-Go criteria and time standards where applicable. The platoon roll-up then summarizes totals: number of individuals tested, % first-time Go, % first-time No-Go.

How to Use DA Form 7660-R? Step-by-Step

  1. Header Information — Fill in Unit, Platoon, and Date (YYYYMMDD).
  2. Vehicle/Crew Data — List vehicles by bumper/VC number and record performance for each crew position.
  3. Task Evaluation — Mark results for platform-specific and common tasks.
  4. Summary Metrics — Calculate and enter # of Individuals Tested, % First-Time GOs, and % First-Time NO-GOs.
  5. Roll-Up — Use this to feed into company-level forms like DA Form 7661-R for higher headquarters reporting.

Units often complete this during consolidated prerequisite testing windows (e.g., T-6 to T-week before major gunnery events).

Why This Form Matters for HBCT Readiness?

  • Standardization — Ensures consistent evaluation across Abrams, Bradley, and supporting platforms in the HBCT.
  • Data-Driven Training — Platoon leaders quickly spot trends (e.g., recurring misfire drill issues) and adjust training plans.
  • Progression Gate — Successful completion of Table I (along with GST) is typically required before live-fire tables (IV-VI for crews).
  • Documentation — Supports unit historical records, inspections, and after-action reviews.

In modern large-scale combat operations training, strong performance on Table I correlates with better outcomes in collective platoon and company gunnery tables.

  • DA Form 7662-R — GST Platoon Roll-Up
  • DA Form 7661-R — Table I Company Roll-Up
  • DA Form 7664-R — Individual Crew Critical Skills Test Scoresheet
  • DA Form 7665-R — GST Company Roll-Up

These forms create a clear audit trail from individual skills to platoon and company proficiency.

Best Practices for U.S. Army Units

  • Train tasks in the motor pool and with vehicle simulators before formal testing.
  • Use Master Gunners to standardize evaluator techniques.
  • Conduct after-test debriefs focusing on No-Go trends.
  • Maintain digital and hard copies per unit SOP and AR 25-400-2 (Army Records Management).
  • Integrate with broader Integrated Weapons Training Strategy (IWTS) and TC 3-20.31 guidance.
