1.0 Scope

This System Requirements Document (SRD) describes the requirements for the Tank variants (TV) and Tank Engineering Variants (TEV) kit. When the driver’s compartment installs on a Common Driver Trainer (CDT) platform, the collective system becomes a Common Driver Trainer Tank Variant (CDT TV) that will provide training for M1A1 SA and M1A2 System Enhancement Package version 2 (SEPV2) Abrams tracked vehicle drivers. The CDT TV will provide initial entry training at the armor school as well as sustainment and advanced training at the fielded sites. The trainer will enable training in the critical driver tasks that repetitively train in a simulator. It will also allow training of driver tasks that are dangerous and/or infrequently trained in the "real world" (e.g. driving on ice, fording streams, driving under blackout conditions and driving down a steep embankment when coming off an improved road).

The TEV kit includes Assault Breacher Vehicle (ABV) and Joint Assault Bridge driver’s compartment hardware and software and vehicle commander’s station hardware and software. When this kit installs on a CDT TV platform, the collective system becomes a Common Driver Trainer Tank Engineering Variant (CDT TEV) that provides training for the Assault Breacher Vehicle (ABV) and Joint Assault Bridge (JAB) tracked vehicle drivers and vehicle commanders. It will provide initial entry training at the engineer school. The trainer will enable training in the critical driver and crew interaction tasks that repetitively train in a simulator. It will also allow training of driver and crew interaction tasks that are dangerous and/or infrequently trained in the "real world", e.g.:

a. Driving on ice

b. Fording streams

c. Driving under blackout conditions

d. Driving down a steep embankment when coming off an improved road

e. Deployment and recovery of assault bridges

f. Operation of the Linear Detonation Charge System (LDCS)

g. Plowing

h. Breaching operations
