Quick Summary

  • Official Gateway URL: https://dtms.army.mil (Supporting resources hosted via the Army Training Network at https://atn.army.mil).
  • Primary Authentication: Department of Defense Common Access Card (CAC) via EAMS-A single sign-on.
  • Account Provisioning Rule: Unit DTMS Managers must build new profiles using the Soldier's ICAM Legacy UID (former AKO username), never their @army.mil enterprise email.
  • Official Support Desk: Army Training Management System (ATMS) / TMD Help Desk at (877) 241-0347 or (913) 684-2700 (DSN 552-2700).

To log in to the U.S. Army Digital Training Management System (DTMS), navigate directly to https://dtms.army.mil using a CAC-enabled workstation, select either the DTMS Live Site or DTMS Practice Site, and authenticate through EAMS-A using your Common Access Card (CAC) Authentication Certificate and PIN. Overseen by the Training Management Directorate (TMD) at Fort Leavenworth, DTMS serves as the Army's primary web-based platform for planning, recording, and assessing unit and individual training readiness under FM 7-0 doctrine. Unit Commanders, First Sergeants, S-3 Operations staffs, and Unit Training NCOs rely on this portal daily to input Army Combat Fitness Test (ACFT) scores, update individual weapons qualifications, track height and weight compliance, and submit Mission Essential Task List (METL) assessments that feed directly into the Net Unit Status Report (NetUSR) and IPPS-A.

Required CAC Credentials & ICAM Legacy UID Setup

How to Sign In to the Official DTMS Army Gateway

  1. Step 1 โ€” Verify Your Legacy UID (First-Time Users Only): Before requesting access from your S-3 or Battalion DTMS Manager, sign in to the ICAM Portal via EAMS-A with your CAC. Locate the Legacy User's Identification (UID) field (your old AKO format username) and provide that exact string to your training manager so they do not mistakenly register your @army.mil address.
  2. Step 2 โ€” Open the Official DTMS Gateway: Insert your CAC into your smart card reader and navigate to https://dtms.army.mil in Microsoft Edge or Chrome. Review the Department of Defense Information System (IS) security banner and click OK or Accept to proceed.
  3. Step 3 โ€” Select Your Operational Environment: On the DTMS landing page, choose between two distinct portals: click DTMS Live Site to record official unit training data and modify readiness records, or click DTMS Practice Site to test scheduling layouts and run mock training reports without altering real operational data.
  4. Step 4 โ€” Authenticate via EAMS-A Single Sign-On: When redirected to the Enterprise Access Management Service-Army (EAMS-A) login screen, select the CAC / PKI Login option. Choose your non-email Authentication / PIV Certificate from the browser security prompt and enter your 6-to-8-digit CAC PIN.
  5. Step 5 โ€” Confirm Unit Hierarchy Assignment: Once authenticated, verify that your dashboard displays your correct Unit Identification Code (UIC) and assigned operator permissions (e.g., Unit Admin, Training Manager, or Commander tab access) before inputting Soldier records.

Fixing Infinite Redirect Loops & Account Provisioning Errors

โš ๏ธ ERR_TOO_MANY_REDIRECTS (Infinite Redirect Loop After Clicking Live or Practice Site)

Cause: This is the #1 technical lockout in DTMS. It occurs when a Unit DTMS Manager builds your user profile using your Army 365 Enterprise Email ([email protected]) instead of your ICAM Legacy UID, or when your existing profile remains tied to an outdated UIC after a Permanent Change of Station (PCS).

Solution: Clearing cookies alone will not fix an improperly provisioned account. Log into the ICAM Portal, copy your exact Legacy UID, and have your S-3 DTMS Manager delete the corrupted email-based profile and rebuild your account using the Legacy UID. Afterward, close all browser windows, relaunch Edge in an InPrivate window, and log back in.

โš ๏ธ EAMS-A Certificate Selection Failure or 403 Forbidden Access Denied

Cause: Your browser cached a 16-digit PIV/Email encryption certificate or an expired CAC certificate during the TLS handshake, preventing EAMS-A from reading your active DoD PKI credentials.

Solution: In Microsoft Edge, navigate to Settings > Privacy, search, and services > Security > Manage certificates. Clear the SSL state via Windows Internet Options > Content tab > Clear SSL state, re-seat your CAC in the reader, and explicitly select the certificate listing Client Authentication when prompted.

โš ๏ธ Soldier Missing from Unit Training Roster or ACFT/Weapon Scores Not Syncing to IPPS-A

Cause: DTMS does not control personnel slotting; unit rosters inside DTMS are populated downstream from authoritative HR assignments in the Integrated Personnel and Pay System - Army (IPPS-A).

Solution: Verify with your Battalion S-1 that the Soldier has been formally arrived and slotted against the exact sub-UIC in IPPS-A. Allow 24 to 48 hours for the automated data bridge between IPPS-A and DTMS to refresh before attempting to input training records.

Frequently Asked Questions

Q: Can every Soldier log in to DTMS to view their own ACFT and weapons scores?

No. Direct login to https://dtms.army.mil is restricted to command teams, S-3 personnel, and designated Unit DTMS Managers who hold provisioned operator accounts. Individual Soldiers should view their personal training records, weapons qualifications, and ACFT data through the Army Training Information System (ATIS) portal, IPPS-A, or their Soldier Talent Profile (STP).

Q: How do I find my ICAM Legacy UID so my S-3 can create my DTMS account?

Sign in to the ICAM Portal via EAMS-A using your CAC and view your personal identity profile. Look for the field labeled Legacy User's Identification (UID)โ€”which reflects your legacy AKO username formatโ€”and provide that exact identifier to your unit's DTMS Manager.

Q: Can I access the DTMS portal from a home computer or mobile phone?

DTMS does not offer a dedicated iOS or Android mobile app and is designed for desktop workstations. However, authorized managers can access https://dtms.army.mil from a personal Windows or Mac computer equipped with a USB CAC reader, provided DoD root certificates are installed or they connect through the Army Azure Virtual Desktop (AVD) environment.

Q: Where can I find official DTMS operator tutorials and training courses?

All official self-help guides, video walk-throughs, and system updates are hosted inside the DTMS Knowledge Base on the Army Training Network (ATN) at https://atn.army.mil. The Training Management Directorate (TMD) also hosts monthly live DTMS Operators Courses via Microsoft Teams and quarterly in-person manager courses at Fort Leavenworth.

Wrap Up

Maintaining accurate unit readiness metrics inside the Digital Training Management System (DTMS) begins with proper account provisioning and strict CAC certificate hygiene. Always ensure your S-3 training manager builds your operator profile using your ICAM Legacy UID rather than your enterprise email address to prevent redirect loops. If you encounter persistent UIC routing conflicts or METL synchronization issues, consult the DTMS Knowledge Base on https://atn.army.mil or call the Fort Leavenworth ATMS Help Desk directly at (877) 241-0347.
