Active Duty Training (ADT) and Annual Training (AT)

What ADT and AT Are

Per MCRAMM Chapter 3 Section 3, Active Duty for Training (ADT) is reservist active duty performed for the primary purpose of training. Annual Training (AT) is a specific subset of ADT with annual recurrence.

These differ from regular drill in three critical ways.

1. The reservist is in active duty status (BAH, BAS, full active pay).
2. Orders process through MROWS, not Drill Manager.
3. Duration runs days to weeks, not hours.

Annual Training (AT)

AT is the year's primary block of active duty training. Per 10 USC 1230110 USC 12301(b) and MCRAMM Chapter 3.

• Standard duration of 12 to 14 consecutive days
• Authorized annually for SMCR units
• Performed at the unit, a training facility, or a deployment site
• Active duty pay and entitlements during the AT period
• Earns one retirement point per day

Active Duty for Training (ADT)

ADT is broader than AT. Used for specific training requirements beyond the annual AT period.

• School attendance (formal MOS schools, leadership courses)
• Cross-training with active duty units
• Specialized exercises requiring extended training
• Pre-mobilization training preparation

ADT periods process orders through MROWS like AT.

Pay Treatment

Both AT and ADT process at active duty rates.

• Full base pay (no 1/30th calculation)
• BAH at the duty location rate (with-dependents or without)
• BAS at active duty rate
• Per diem and travel reimbursement per JTR
• Special pays where applicable (jump, dive, flight)

This is meaningfully more pay than equivalent IDT periods.

Conditions and Authorization

Per MCRAMM, AT and ADT require.

• Specific orders authorizing the active duty period
• Funding source identified (typically Reserve Personnel Marine Corps or specific exercise funding)
• Member screening for medical and admin readiness
• Pre-AT or pre-ADT briefing on duties and expectations

Performance Steps for AT Processing

Step 1 - Generate Orders in MROWS

Before AT, orders must exist.

• Open Marine Reserve Orders Writing System (MROWS)
• Identify the AT period dates and location
• Build orders for each member attending
• Include funding citation
• Route for command signature

Step 2 - Process Pre-AT Admin

Within 30 days of AT start.

• Verify member medical readiness (current PHA, dental, immunizations)
• Confirm member dependent status and BAH expectations
• Process any pay status changes (special pays, extra duty)
• Brief members on travel reimbursement procedures

Step 3 - Process Active Duty Status Change

When AT begins, the member's status shifts to active duty.

• Submit UD/MIPS active duty start transaction
• BAH and BAS activate at active duty rate
• Drill pay codes deactivate for the period

Step 4 - Process During-AT Actions

During AT, the unit functions like an active duty unit.

• Daily accountability via JPERSTAT
• Pro/Con marks if quarterly mark date falls during AT
• Promotion warrants if scheduled
• Awards for AT-specific accomplishments

Step 5 - Process AT End and Return to Reserve Status

When AT ends, status reverts.

• Submit UD/MIPS active duty end transaction
• BAH and BAS revert to reserve status (no pay during inactive periods)
• Drill pay codes reactivate for the next drill weekend

Step 6 - Travel Voucher Processing

Members submit travel claims for AT.

• DD Form 1351-2DD Form 1351-2 travel voucher
• Process through Defense Travel System (DTS)
• Per diem, mileage, and lodging reimbursement per JTR
• Verify all entitlements properly claimed

Common AT Errors

These hit most often on AT processing.

1. No AT orders generated. Member showed up but admin never built MROWS orders. Member technically performs without authority. Fix by issuing retroactive orders with command approval.
2. Pay treatment as IDT. AT processed at drill pay rate instead of active duty rate. Pay shorted. Fix by processing AT at active duty rate retroactively.
3. BAH not started. Member entered AT but BAH never activated. Pay shorted by the BAH amount for AT duration. Fix via UD/MIPS retroactive transaction.
4. Travel voucher missed deadline. DTS voucher not submitted within 5 days of AT end. Late voucher creates audit issues.
5. Status reversion delayed. AT ended but active duty UD/MIPS transaction never submitted. Member overpaid for time after AT. Creates pay debt.

Active Duty for Operational Support (ADOS)

ADOS is a related but distinct category. Per MCO 1001.59MCO 1001.59.

• ADOS is reservist active duty for operational support, not training
• Used for specific operational missions
• Processes through MROWS like AT and ADT
• Pay and entitlements at active duty rate
• Duration varies by orders

When the I&I receives an ADOS order, treat similarly to AT for admin processing but track separately for accountability.

Muster Duty Active Duty Other Than for Training

Per MCRAMM Chapter 3 Section 3.3, this is short-duration active duty for purposes other than training. Different from MD as inactive duty (covered separately). This category covers brief active duty for specific operational reasons.

Decision Tree for Order Type

When processing reserve duty orders, walk this.

1. Is duration less than 24 hours? Likely IDT or MD.
2. Is duration multi-day with active duty pay? AT, ADT, or ADOS.
3. Is the purpose primary training? AT or ADT.
4. Is the purpose primary operational support? ADOS.
5. Is the purpose involuntary mobilization? AD under 12302 or 12304.

Coordination Touchpoints

AT and ADT touch many external organizations.

• MARFORRES G-3: AT scheduling and operational requirements
• MROWS administrators: Orders generation and tracking
• Supporting IPAC: Active duty pay processing during AT
• DTS administrators: Travel voucher processing
• Gaining commands: For AT performed at active duty units

Related Roles

AT processing affects every role at the unit.

• Marines receive AT orders, perform AT, submit travel vouchers, and verify pay on LES.
• Leaders at the unit lead AT execution and verify Marine training completion.
• Commanders authorize AT plans, sign MROWS orders, and command the AT period.
