Global Combat Support System-Marine Corps

1. Global Combat Support System-Marine Corps • Global Combat Support System-Marine Corps (GCSS-MC) is an internet based, multi-block program for Logistics Chain Management (LCM) that modernizes the USMC ground Logistics Architecture and Management across retail supply, wholesale supply, equipment maintenance, and repair functions. • GCSS-MC is being fielded incrementally in "blocks," each of which will provide additional capabilities. • GCSS-MC Block 1 provides retail supply and maintenance capability to the MAGTF, and is further segmented into two releases: • Capability Release 1 contains the supply, maintenance, request and service management functionality • Capability Release 2 extends this functionality to Marines operating in deployed environments.

2. GCSS-MC • GCSS-MC/LCM Block 1 will replace existing/legacy systems: • SASSY • ATLASS • MIMMS/PC MIMMS • Delivery of both releases of GCSS-MC Block 1 will occur in a phased approach to the operating forces. III MEF, along with elements of Marine Corps Logistics Command, will be followed by I and II MEFs and Marine Forces Reserve. The supporting establishment will be fielded simultaneously with their associated geographic MEFs.

3. GCSS-MC • GCSS-MC's advantages : • • Improved global and cross-battlefield asset visibility: you’ll know what you have. • • Better materiel readiness: you’ll know if you’re ready for battle. • • Improved speed and accuracy: you’ll be able to trust your data. • • Modern web-based deployable systems: your technology travels with you. • Optimized processes and the automation of many manual tasks: you’ll lose the green log books, the fat books of code, and the stubby pencils. • GCSS-MC provides the capability to see what equipment needs to be repaired, where the parts are located, and who is available to perform the work. • Preventive Maintenance (PM) management will become automated.

4. III MEF GCSS Implementation Progress • III MEF GCSS-MC Implementation Scheme of Maneuver • Cutover activities began Dec 2009; initial cutover started 15 Mar 2010 • Field User Evaluation (FUE) completed 15 Mar-1 June • Initial Operator Test and Evaluation (IOT&E) 21 June - 6 Aug (conducted by MCOTEA) • Next block of cutover scheduled 23 August (8 units in 1st MAW) • Anticipated III MEF rollout to be complete between July-Sep 2011

5. GCSS Cutover Timeline (11 Weeks) • C-11: Cutover team conducts survey of activities, meets with command key personnel. • C-6: Begin user training, inventories, 1st mock conversion, collect Break Report (BR) 100 data • C-5: Cutover team submits BR.100 to GCSS program office, work mock conversion discrepancies • C-4: All priority 12 requisitions stop • C-3: Verify BR.100 data in GCSS-MC, DASF and DPR records match, SABRS and SASSY records match, 05 priority requisitions stop • C-2: Second mock conversion, Billet Identification Codes (BIC) pull for GCSS-MC, upload HR data, 02 requisitions stop • C-1: Self-registration/activation/setup of user accounts, DASF, RO, ROP allowances are correct, final reconciliation with legacy systems for tracking purposes • C-0: Account conversion to GCSS-MC • C+1: Data validation and conduct live transactions

6. GCSS Implementation Training • Satellite GCSS-MC Operations Cell (SGOC) training team will arrive approximately three weeks prior to cutover activities beginning (C-05) • Receive training information in three phases • In-brief • Preparation and education • Unit in-brief will identify schedule for actual dates SGOC training team will provide instruction. • Classroom instruction • Unit will provide a Unit Training Coordinator (UTC) • Recommend the S-3 Chief • Requires MCTMS access (local school entries required) • Be prepared to provide a current Alpha roster of all unit personnel • On-hand strength by T/O Billet • Used to identify roles and required training • Name  Billet  Role  Training • Commander’s Course: CO, XO, AO, RO and key staff members • 2 hour course

7. GCSS-MC Unit Fielding Preparation • Tasks that can be performed ahead of time: • Data cleansing and quality (S/N, on hand qty, relationships) • Correct TAMCN and/or NIIN must match Master Header Information File (MHIF) or data will not convert. • Records must match or data will not convert. • Identify stock locations and sub inventories. • Billet Identification Codes (BIC) assignment (identify which billets will need GCSS-MC training). • Take on-line training • https://gcssmc-sso.csd.disa.mil/gcssmc_portal/training.html

8. Data Quality Concerns • SASSY LUAF/RTLS: Military equipment allowances and on-hand balance reconciliations must include serial and lot controlled details where applicable. • SASSY GABF/LUBF/RTLS: Validation of on-hand balances held within the legacy inventory accounts; must include serial, lot controlled, shelf life and condition details where applicable. • Serial Number Reconciliation: Elimination of duplicates across multiple organizations. Re-serialization of locally serialized items will be required IOT prevent known error conditions. • SASSY MHIF/NSIF/Technical Data Management Systems (TDMS): Combine multiple Local Serial Number (LSN) assignments into a single Marine Corps Serial Number (MCSN) and update accounting records accordingly. Remove inactive records and ensure the unit’s tech data file (Y80) contains the necessary NSN relationships IOT support assignment of items to each organization (also includes local TAMCN issues). Reconcile TDMS/MHIF differences. • SASSY DASF: Conduct reconciliations between DASF and SABRS IOT eliminate erroneous records, process receipts, manage and process exception reports and correct additional DC tasks (RDD, codes, zero QTY) as appropriate. • SASSY Automated Information Table (AIT)/MDC DODAAD: Validate and update addresses, add TAC 2 Addresses, assign responsible party UIC(s), update RIC entries, and remove unnecessary AAC(s) from the SASSY Automated Information Table. • MCTFS/ODSE: Update Marine information to include accurately assigned Billet Identification Codes (BIC) to each individual within a unit.

9. GCSS-MC GCSS-MC End State: Fully-leveraged deployable, integrated, and sustainable 21st century technology supplying the Marine with the right logistics data at the right time, both in garrison and on the battlefield. The Logistics Modernization (LogMod) website is updated regularly with new information on GCSS-MC’s development, testing, and implementation. https://logmod.hqmc.usmc.mil/
