10	1. The Type 74 tank (hereinafter referred to as "tank") is used to destroyer tanks, armoured vehicles, and other ground targets as the backbone of a armoured assault force.
11	2. Main structure / function: The tank is a armoured tracked vehicled with a turret equipped with a 105 mm tank gun, a 12.7 mm heavy machine gun, and a 7.62 mm machine gun coaxial with the 105 mm tank gun mounted on the upper surface of the box-shaped body. Its main structure and functions are as follows in addition to those shown in Attached Figure 1:
12		(1) There are four crew members: the commander, the gunner, the loader, and the driver.
13		(2) Maneuvering is easily performed by the large engine control surface, speed reducer control device, various switches, and etc located around the driver's seat; and the power to the engine / gearbox are integrated with the connection mounted on the rear part of the vehicle body. It is transmitted from the steering machine to the starting wheel at the rear of the body via the final reduction gear.
14		In addition, the vehicle height and vehicle body tilt are converted by controlling the amount of oil in the hydraulic spring suspension system by means of an electric signal from the driver's seat or inside the turret.
15		(3) Shooting shall be carried out quickly and precisely by sights, a laser rangefinder, a ballistic calculator, a gun stabilizer, firing devices, and etc located around the gunner's seat and the commander's seat. The movable focus mirrors of the 105 mm tank gun, the gunner's sighting periscope, and the commander's sighting periscope are servo-controlled by the output signals of the laser rangefinder and other ballistic calculators that respond to the inputs.
16			In addition, the 105 mm tank gun is kept stable in both direction and height by the gun stabilizer regardless of the shaking of the tank.
17		(4) For communication, a vehicle radio is installed at the rear of the turret and an on-board telephone is installed at the rear of the vehicle body to enable wireless communication and in-vehicle / outside communication.
18		(5) The night-vision device for maneuvering is attached to the front part of the vehicle body and is used for driving at night.
19		In addition, the aiming night-vision device (Floodlight unit) can be attached to the turret and is used for night shooting in combination with the direct aiming sight. [Type the Type 74 (G)] The aiming night-vision device can be attached to the front of the turret and is used for target seraching and aiming with heat ray images.
20		[For the Type 74 (G)] Direct aiming sight is also used for night shooting.
21		(6) In addition to vehicle security, tanks ensure the safety and habitability of occupants during shooting and movining.
22		(7) In addition to installing a CBR (Checmical / Biological / Radiation) protection device, a smoke grenade launcher, and etc, it is possible to cross a river by installing a diving assistance device to allow for diving. [For Type 74 (G)] In addition to being equipped with a laser detection device, a smoke grenade launcher that can be fired in conjuction with the device, a special weapon protection device, and etc, it is possible to cross a river by installing a diving assistance device to allow for diving.
23		In addition [for the Type 74 (G)], a side skirt can be attached to the side of the vehicle.
24		(8) A tank can be equipped with a dozer device consisting of a soil removal device, a hydraulic device, and etc., by modifying part of the vehicle body.
25		(9) Tanks [Type 74 (F) and Type 74 (G] can be equipped with demining rollers according to the Formal R 3603 by installing the additional equipment shown in Appendix 7 and Appendix 1. (Excludes vehicle equipped with a dozer device)

1. The Type 74 tank (hereinafter referred to as "tank") is used to destroyer tanks, armoured vehicles, and other ground targets as the backbone of a armoured assault force.

11

2. Main structure / function: The tank is a armoured tracked vehicled with a turret equipped with a 105 mm tank gun, a 12.7 mm heavy machine gun, and a 7.62 mm machine gun coaxial with the 105 mm tank gun mounted on the upper surface of the box-shaped body. Its main structure and functions are as follows in addition to those shown in Attached Figure 1:

12

(1) There are four crew members: the commander, the gunner, the loader, and the driver.

13

(2) Maneuvering is easily performed by the large engine control surface, speed reducer control device, various switches, and etc located around the driver's seat; and the power to the engine / gearbox are integrated with the connection mounted on the rear part of the vehicle body. It is transmitted from the steering machine to the starting wheel at the rear of the body via the final reduction gear.

14

In addition, the vehicle height and vehicle body tilt are converted by controlling the amount of oil in the hydraulic spring suspension system by means of an electric signal from the driver's seat or inside the turret.

15

(3) Shooting shall be carried out quickly and precisely by sights, a laser rangefinder, a ballistic calculator, a gun stabilizer, firing devices, and etc located around the gunner's seat and the commander's seat. The movable focus mirrors of the 105 mm tank gun, the gunner's sighting periscope, and the commander's sighting periscope are servo-controlled by the output signals of the laser rangefinder and other ballistic calculators that respond to the inputs.

16

In addition, the 105 mm tank gun is kept stable in both direction and height by the gun stabilizer regardless of the shaking of the tank.

17

(4) For communication, a vehicle radio is installed at the rear of the turret and an on-board telephone is installed at the rear of the vehicle body to enable wireless communication and in-vehicle / outside communication.

18

(5) The night-vision device for maneuvering is attached to the front part of the vehicle body and is used for driving at night.

19

In addition, the aiming night-vision device (Floodlight unit) can be attached to the turret and is used for night shooting in combination with the direct aiming sight. [Type the Type 74 (G)] The aiming night-vision device can be attached to the front of the turret and is used for target seraching and aiming with heat ray images.

20

[For the Type 74 (G)] Direct aiming sight is also used for night shooting.

21

(6) In addition to vehicle security, tanks ensure the safety and habitability of occupants during shooting and movining.

22

(7) In addition to installing a CBR (Checmical / Biological / Radiation) protection device, a smoke grenade launcher, and etc, it is possible to cross a river by installing a diving assistance device to allow for diving. [For Type 74 (G)] In addition to being equipped with a laser detection device, a smoke grenade launcher that can be fired in conjuction with the device, a special weapon protection device, and etc, it is possible to cross a river by installing a diving assistance device to allow for diving.

23

In addition [for the Type 74 (G)], a side skirt can be attached to the side of the vehicle.

24

(8) A tank can be equipped with a dozer device consisting of a soil removal device, a hydraulic device, and etc., by modifying part of the vehicle body.

25

(9) Tanks [Type 74 (F) and Type 74 (G] can be equipped with demining rollers according to the Formal R 3603 by installing the additional equipment shown in Appendix 7 and Appendix 1. (Excludes vehicle equipped with a dozer device)

25	(1) Earlier smoke grenades simply were pre-guided by the angle of the smoke launchers and the commander had no assistance in assuring the smoke screen lands where it should. The (G) model upgraded this for the turret to automatically track towards a laser and launch the smoke from there.
26	(2) Until the (G) model, a single automatic fire extinguisher was in the engine compartment while only two portable ones were in the fighting compartment. The (G) installed a automatic fire extinguisher in the fighting compartment to supplement the portable ones.
27	(3) The (G) model added a plate on the idler wheel in order to prevent the tracks from coming loose.
28	(4) A second panel was added in the (G) model for the smoke grenade's laser detector.
29	(5) Originally, the camouflage was a one-tone OD until this was changed to a two-tone dark green-brown in the (C) model for every succeeding one.
30	(6) The tables for these are broken in their respective outlines, this is just guesswork.
31	(7) The different projectiles are as follows:

35			Type 75 HEP-TJ model 1
36			Type 75 HEP-TJ model 2
37		(c) APDSFS-T / APFSDS-T (armour-piercing discarding sabot fin-stabilized tracer / armour-piercing fin-stabilized discard sabot tracer)
38			M735 APDSFS-T / APFSDS-T
39			Type 93 APFSDS-T
40		(d) HEAT-T (high-explosive anti-tank tracer)
41			No HEAT-T projectile exists
42		(e) HEAT-MP-T (high-explosive anti-tank multipurpose tracer)
43			Type 91 HEAT-MP-T
44	(8) APDSFS-T is not mentioned in the Provisional Outline (1974) for the Type 74, but it is mentioned in the Formal Outline (1993). Despite it being either added or already included but not mentioned before, the ballistic computer still didn't have the capability to calculate APDSFS-T.
