5. What is PGS? Strap-on laser-based training device that allows full crew interaction when conducting gunnery training. Allows crew to train with all components of BFV’s fire control system.

6. PGS Features Full fire control interface. Realistic simulation of ballistics and time of flight for service AP, HE, and COAX ammunitions. Simulates TOW Basic, TOW2, and TOW2B. Visual effects are displayed over the ISU, ISUCE or backup sight eyepieces. Simulation of 25 mm and Coax weapon effects. Simulated ammo transfer from the hull to turret. Transparent to crew. Intercom sound effects of firing of TOW, 25 mm gun, COAX, and of target effects.

7. PGS Capabilities Engage stationary or moving targets from a stationary or moving vehicle. Panel gunnery and force-on-force capability. TOW only training (live fire 25mm and COAX). Tracking training. Scaled gunnery training (1/2 and 1/10). Tamper resistant. Full AAR capability. Programmable ammunition loads.

8. PGS Compatibility Tank Weapon Gunnery Simulation System (TWGSS). Precision Gunnery System (PGS) for LAV. Cooperative MILES - equipped systems with retro reflector units installed. Non-cooperative MILES - equipped systems without retro reflector units installed. Panel targets equipped with retro reflector units and/or LTIDs (Laser Target Interface Device). Interoperable with Thru-sight Video.

18. General Safety Regulations Mount and dismount over left front or through back ramp. Maintain three (3) points of contact on top of vehicle. Follow unit smoking SOP. Do not go over or under gun barrel. During installation and removal: –TURRET TRAVERSE DRIVE SELECT LEVER to MANUAL –TURRET TRAVEL LOCK to LOCKED –MASTER POWER switch OFF –TURRET POWER switch OFF Use proper hearing protections at all times. Cables must be connected by properly trained personnel. If ATWESS is used, observe all safety regulations.

19. Laser Safety PGS uses a conditionally eye safe laser (Class 3A) WARNING Transceiver unit has an eye-safety classification of 3A. During operation, DO NOT view transceiver unit with an unaided eye for an extended period of time. DO NOT AT ANY TIME view transceiver unit with an aided eye, (i.e., optics which magnify) from a distance less than 25 meters.

23. Closing Statement This block of instruction has prepared you to understand the concepts of PGS and the safety procedures pertaining to its operation.

24. Reason To use PGS to its full potential, the vehicle must be properly prepared for PGS training.

25. Training Objective Given an operational BFV with BII and a 25mm boresight kit, you will demonstrate the following tasks to prepare the vehicle for PGS training: Conduct prep-to-fire checks Boresight vehicle Prepare the BFV for PGS installation

26. Prepare Vehicle for PGS Training Conduct prep-to-fire checks and services Boresight turret weapons Prepare vehicle specific equipment

27. Preparation of Vehicle-Specific Equipment for Installation TURRET TRAVERSE DRIVE SELECT LEVER to MANUAL TURRET TRAVEL LOCK to LOCKED TURRET POWER switch OFF MASTER POWER switch OFF Inspect and clean DTP connectors Remove rear periscope at commander’s position Remove commander’s and gunner’s browpads Adjust vehicle load plan

28. Summary Conduct prep-to-fire checks and services Boresight turret weapons Prepare vehicle specific equipment

29. Closing Statement To get the desired training result from PGS, you must first properly prepare the BFV for PGS installation.

31. Reason Training hours are lost when unit personnel draw training equipment that is incomplete or unserviceable. Many of these hours could be saved if unit personnel know what to look for and how to check the equipment.
