Scope Identification This System Specification establishes the System-level technical performance, design, development, integration, verification and production requirements for the Conduct of Fire Trainer platform, herein known as the Bradley Conduct of Fire Trainer (COFT) trainer.
The Bradley COFT trainer replicates the performance of the M2/M3 Operation Desert Storm-Situational Awareness (ODS-SA) Bradley Fighting Vehicle (BFV) and the M2/M3A3 BFV enabling the crew to operate a BFV entity in a synthetic environment.
It trains and sustains the Bradley Gunner and Commander in critical gunnery skills as required for direct fire engagements.
The Bradley COFT Trainer has three (3) configurations:
| 1. | Institutional/classroom environment - unsheltered. |
| 2. | Mobile - Environmentally controlled mobile trailer. |
| 3. | Table Top Trainer - Portable, hard-sided transit cases |
Each trainer configuration consists of a crewstation, an image generator, computational equipment, and an Instructor Operator Station, which make up the basic Training Device subsystem as shown below. Throughout this document the basic Training Device is referred to as the "trainer". The Mobile configuration has an additional subsystem called the Trailer.

| c. | Depending upon the ammo reverse condition, LO AMMO thresholds shall apply as follows: |
| (1) | Ammunition starting out with 70 rounds loaded shall have a LO AMMO threshold of 35 rounds. |
| (2) | Ammunition starting out with 230 rounds shall have a LO AMMO threshold of 55 rounds. |
| (3) | Coax shall always have a LO AMMO threshold of 110 rounds. |
| (4) | There shall be no LO AMMO threshold for TOW. |
| d. | Upon reaching a given LO AMMO threshold, the LO AMMO indicator shall flash and the firing of given ammunition shall be suppressed. The crew may choose alternate stowed ammunition to use or continue to use the selected ammunition with the LO AMMO condition after pressing the LO AMMO OVRD switch. |
| e. | Pressing the LO AMMO override switch when flashing for the selected ammunition shall cause the LO AMMO indicator to stop flashing and become steadily illuminated. This shall also allow the continuation of firing the selected ammunition until no more rounds of that ammunition are loaded (loaded ammo counter reaches zero). |
| f. | Reload capabilities for given ammunition shall be enabled when at least one round of the selected ammunition has been fired and the second situation has started. |
| If stowed ammunition remains, the transfer shall take place by adding the necessary number of rounds to fill the appropriate ammunition box to capacity. This has the effect of reducing the stowed ammunition counter by the number of rounds added to the loaded ammunition counter. | |
| If there is insufficient stowed ammunition to fill a given box to capacity, but some stowed ammunition remains, the remaining stowed ammunition shall be added to the loaded ammunition counter and the stowed ammunition counter shall be set to zero (0). | |
| If there is no remaining stowed ammunition for given ammunition, no transfer shall take place. | |
| g. | Reload times shall be dependent on the number of loaded rounds remaining as outlined below: |
| (1) | If either 25mm ammunition is below the LO AMMO threshold, the reload time shall be 30 seconds for given ammunition below LO AMMO threshold. |
| (2) | If either 25mm ammunition is at or above the LO AMMO threshold, the reload time shall be 15 seconds for given ammunition above LO AMMO threshold. |
| (3) | For Coax, if the remaining loaded ammunition is below the LO AMMO threshold, the reload time shall be 16 seconds. |
| (4) | For Coax, if the remaining loaded ammunition is at or above the LO AMMO threshold, the reload time shall be 8 seconds. |
| h. | During any 25mm reload process the No-Fire-Zone and Open Hatch lights shall illuminate during reloading process, and extinguish upon completion of reloading process. Coax and 25mm ammunition may be loaded simultaneously. The conditions for reloading 25mm ammunition and Coax ammunition are listed below: |
| (1) | The 25mm reload process shall require the crew to perform the following actions: |
| (a) | Set ASR switch to SAFE. When ASR switch is in SAFE position, trigger switches are inactive. RESET position deselects any selected weapon. |
| (2) | Traverse turret to 4350 mils +/-50 mils for the 70 round ammunition box (AP unless ammo reverse selected), 2100-2200 mils +/-50 mils for the 230 round ammunition box (HE unless ammo reverse selected). |
| (a) | For AP reload, the table top configuration will require the crew to traverse to the 8 o’clock position as indicated on the turret position indicator (TPI). (There is no Azimuth indicator to determine mils.) |
| (b) | For HE reload, the table top configuration will require the crew to traverse to the 4 o’clock position as indicated on the turret position indicator (TPI). (There is no Azimuth indicator to determine mils.) |
| (3) | Engage turret travel lock. (mobile and institutional configuration only) |
| (4) | Turn off turret drive power. |
| (5) | Wait for designated amount of time (15 or 30 seconds), depending on loaded ammunition amount |
| (6) | No-Fire-Zone and Open Hatch shall be illuminated. |
| (7) | Turn on turret drive power. |
| (8) | Disengage turret travel lock and resume operations. (mobile and institutional configuration only) |
| i. | The Coax reload process shall require the crew to perform the following actions (mobile and institutional configurations only): |
| (1) | Set ASR switch to SAFE. When ASR switch is in SAFE position, trigger switches are inactive. RESET position deselects any selected weapon. |
| (2) | Set Turret Drive to Off. |
| (3) | Move smart display. |
| (4) | Open coax access doors |
| (5) | Manually set Coax safety switch to safe. |
| (6) | If ammo runs out, pull charging handle and manually set Coax safety switch to safe. |
| (7) | Wait for designated amount of time (8 or 16 seconds, dependent upon loaded Coax amount). |
| (8) | Manually set Coax safety switch to fire after reload is complete. |
| (9) | Close Coax access doors and resume operation. |
| j. | Operation of the grenades launcher shall be simulated as described in the System Control Box section. Firing shall be limited to one grenade salvo per exercise. |

a. TOW engagements shall have an exposure time of 50 seconds.
b. A TOW engagement shall have only one armored target at a range of 1000–3750 meters.
1) TOW targets shall be classified as short range (1000–1799 meters) and long range (1800–3750 meters).
2) TOW engagements shall select short range TOW targets 10% of the time and long range TOW targets 90% of the time.
c. Required Performance Measures (RPM) exercises shall have one TOW day and one TOW night engagement.
d. Preliminary, Crew and Advanced exercises shall include random TOW targets as specified in the SIO Exercise Parameters screens.
e. RPM exercises shall enforce the following range requirements:
1) 7.62mm coaxial machine gun – short range: 0–399 meters
2) 7.62mm coaxial machine gun – long range: 600–900 meters
3) 25mm main gun – short range: 0–399 meters
i. Short range 25mm main gun targets shall be light armored targets.
4) 25mm main gun – long range: 1800–2200 meters
f. RPM exercises shall randomly include a degraded engagement that requires the commander to engage targets with the auxiliary sight.
g. The “EXPENDED” boxes in 8.f., 9.f., 10.f. and 11.f. of the Common Crew Score Sheet shall list the number of authorized ammunition fired at the target followed by a label and counts of all other ammunition fired.
1) Example: 4 / 1-HE, 25-7.62
h. COFT shall automatically detect and apply the following crew penalties:
1) AZ-08 (Fire main gun at troops) – Applied if a 25mm round is fired at active troops targets less than 900 meters.
2) AZ-09 (Failure to raise the TOW in defense or TCP) – Applied if there are active targets in a defensive situation and the TOW launcher is not raised.
3) DQ-03 (Fire TOW from defilade) – Applied if a TOW is fired when the OwnVehicle is in the defilade position.
4) DQ-04 (Negligent Discharge) – Applied if there are no active targets and a weapon is fired.
i. If this crew penalty occurs between engagements, then it shall be applied to the next engagement.
i. An IO/SIO shall not have the ability to remove crew penalties AZ-08, AZ-09 and DQ-04 when they have been automatically applied by the Bradley COFT system.
Preliminary, Crew and Advanced Exercise Scoring Preliminary, crew and advanced exercises shall be scored according to TC 3-20.31 Training and Qualification, Crew.
Special Purpose Exercise Scoring Special purpose exercises shall have no more than two targets per situation and shall be scored as described in the following paragraphs.
Detect (Crew Search) special purpose exercises shall be scored as follows:
| a. | Search exercises shall receive a Trained (T) rating if an average of less than 1.0 error per 10 seconds is achieved. |
| b. | Search exercises shall receive a Needs Practice (P) rating if an average of 1.0 - 1.5 errors per 10 seconds is achieved. |
| c. | Search exercises shall receive an Untrained (U) rating if an average greater than 1.5 errors per 10 seconds is achieved. |
Detect (Target Location) special purpose exercises shall be scored as follows:
| a. | Location exercises shall receive a Trained (T) rating if all targets are located in 80% or more of the situations in the exercise. |
| b. | Location exercises shall not have a Needs Practice (P) rating. |
| c. | Location exercises shall receive an Untrained (U) rating if all targets are located in less than 80% of the situations in the exercise. |
Identification special purpose exercises shall be scored as follows:
| a. | Identification exercises shall receive a Trained (T) rating if 80% or more of the targets in the exercise are correctly identified. |
| b. | Identification exercises shall receive a Needs Practice (P) rating if greater than 70% and less than 80% of the targets in the exercise are correctly identified. |
| c. | Identification exercises shall receive an Untrained (U) rating if less than 70% of the targets in the exercise are correctly identified. |
Decide (Target Determination) special purpose exercises shall be scored as follows:
| a. | Determination exercises shall receive a Trained (T) rating if all targets are determined correctly in 80% or more of the situations in the exercise. |
| b. | Determination exercises shall not have a Needs Practice (P) rating. |
