<!-- ''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.'' -->
+
<!-- Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armament separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Tips for preserving survivability should be saved for the "Use in battle" section.
  
−
The M60A1 is ostensibly well-protected for a battle rating 8.3 medium tank. From the front, it can resist most types of full-calibre armour-piercing shells, even at the muzzle. Across the turret, line-of-sight armour thickness varies from approximately 200-440 mm, sufficient against all types of 105 mm APDS. Across its hull, line-of-sight protection ranges from 220 mm over the upper glacis, to 280mm on the lower glacis. The upper glacis may be penetrated from 100 mm and 105 mm APDS from ranges inside of 1,000 m, while the lower glacis is completely immune to those shells. The M60A1's own 105 mm M728 APDS can defeat the upper glacis even at 2,500 m, but the lower glacis can reliably stop M728 at ranges exceeding 1,500 meters.
+
If necessary, use a graphic template to show the most well-protected or most vulnerable points in the armour. -->[[File:Pr123bis.png|thumb|X-Ray view of the Pr. 123bis showing key components that are prone to be damaged when taking enemy fire.]]
 +
The Pr. 123bis doesn't have any armour in the game. When under fire, it is almost certain that an opponent will disable your engines and/or set you on fire (see image on the right). However, you will very rarely be destroyed due to an ammunition explosion.
  
−
The M60A1 is at risk of being engaged with APFSDS, HEAT, and large-calibre (>105 mm) APDS shells, which may easily bypass its protection, despite being stronger than average. The M60A1 also features numerous weak spots that make it vulnerable to vehicles that would not normally be expected to penetrate its armour. In particular, the mantlet, commander's cupola, and turret ring are vulnerable to APCBC shells, which can instantly destroy the tank upon detonation inside of the vehicle. The sloped turret roof is easily defeated by APFSDS and the vehicle's own M728 APDS, but with some luck, it can cause HEAT-FS and HESH shells to bounce harmlessly off.
+
=== Mobility ===
 +
<!-- Write about the ship’s mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward speed and reverse speed. -->
 +
The Pr. 123bis can reach speeds over 120 km/h in AB and around 90 km/h in RB and SB. Backwards, the Pr. 123bis can reach -45km/h, so there should be no trouble reaching strategic points first or at the same time as the lighter boats. The Pr. 123bis turns very quickly, a tactic which should be used to flank opponents and destroy them with machine guns. Lastly, it is unwise to come to a full stop, due to the fact the ship becomes a "sitting duck", easy to pick off by enemy ships or aircraft.
  
−
The vehicle's armour is optimized for head-on protection. The turret's line-of-sight thickness quickly decreases as more of its side profile is exposed. Likewise, the thin side armour of the hull may be easily overmatched and is also insufficient to protect against most armour-piercing autocannon shells, such as 35 mm DM23 APDS. The roof is resistant to most types of armour-piercing bullets or shells fired by aircraft, but specialized munitions such as German Mk103 30 mm HVAP, or 50 mm AP, will penetrate the M60A1's 20-30 mm thick roof.

<!--Provide information about the characteristics of the primary armament. Evaluate their efficacy in battle based on their reload speed, ballistics and the capacity of their shells. Add a link to the main article about the weapon: <code><nowiki>{{main|Weapon name (calibre)}}</nowiki></code>.
  
−
When facing an M60A1 head-on, a shell penetrating the left side of the turret may incapacitate the gunner and commander. A follow-up shot to the right side of the turret may strike the loader and first-stage ammo stowage, while a shell to the middle of the hull may incapacitate the driver. Shells aimed at the right side of the vehicle, when being faced head-on, present the greatest chance of setting off ammunition.
+
Broadly describe the ammunition available for the primary armament, and provide recommendations on how to use it and which ammunition to choose.-->
  
−
When facing an M60A1 from the side, shells penetrating the turret bustle, or hull between the front and middle return rollers, may strike the vehicle's large supply of first-stage ammunition. Some M60A1 drivers may select a reduced ammunition load, so although shells which strike the driver's compartment may incapacitate the driver, they cannot be guaranteed to set off ammunition. Otherwise, shells aimed at the turret between the bulbous rangefinder housing, and before the area where the 25mm flat roof plate meets the sloped 48 mm roof plate, have the greatest chance of incapacitating the entire turret crew.
+
Primary armament composes of two, dual mounted [[DShK (12.7 mm)|DShK]] heavy machine gun turrets with one located at the stern and the other at the centre of the vessel just above and behind the bridge. Note that the turret at the stern is obstructed when pointed towards the bow due to the other turret therefore somewhat restricting fire coverage. The turret just behind the bridge has near 360° though it is slightly obstructed by the mast when pointing towards the bow.
  
−
'''Armour type:'''
+
The DShK 12.7 mm guns provide good firepower and rate of fire against similarly sized ships and somewhat larger ships thanks to its heavy calibre. They have an ammunition capacity of 1,000 rounds with reloads taking ~4.7 seconds. Available belts to research include the high explosive incendiary (HEI) and armour piercing incendiary tracer (APIT) rounds.

The Pr. 123bis carries two 450 mm wet-heating 45-36NU torpedoes. They have a range of 3 km at a speed of 78 km/h or a range of 6 km at 73 km/h with the Torpedo Mode module installed. They are placed at the bow of the boat and fired out already at speed, so you can surprise your opponents with your torpedoes, unlike early American boats, which simply throw the torpedoes to their sides.
−
* Belly armour is 19 mm in the front, 13 mm in the rear.
 
−
* 15 mm RHA plate between the engine and crew compartment.
 
  
−
=== Mobility ===
+
''Be careful with your torpedoes!'' Due to torpedoes being fired out of their tubes at an upwards angle, this means that your torpedoes might over-shoot (literally) any boats which are passing right in front of the Pr. 123bis.

<!-- Depth charges, mines, rocket launchers and missiles are also effective in skilled hands and can be an unexpected surprise for an opponent. Evaluate the ammunition of this type of armament and rate its performance in combat. -->
 +
The Pr. 123bis can carry 6x BB-1 depth charges, which can be used as timed mines to damage/destroy tougher enemies. You can place depth charges around a capture point if you get there first, or in front of an enemy.
  
−

The Pr. 123bis is one of the first Russian boats that get decent firepower, which can destroy its opponents very quickly. Moreover, it gets two torpedoes, which are fired forwards at speed (can be an advantage, but also a disadvantage). All of that weaponry is placed on a motor boat which can reach very high speeds. It's a boat that will help you grind out USSR rank I fleet.

==== Ammunition ====
+
The Pr. 123bis strikes a balance between speed and weaponry. At its low battle rating, the two dual 12.7 mm machine guns reliably destroy all light boats, experiencing difficulty only in a full up-tier. For the most part, the Pr. 123bis should be used as a flanker. Your machine guns destroy compartments with 3-5 bursts, and if you get the first shot on most of your opponents, they are most likely going to die very soon after. However, if you meet tougher opponents, it is viable to simply cross the map around the flank, (ignoring the lighter boats) while the opponents are focused on their front, and fire your torpedoes at their sides (best done when up close and personal).

As a rule of thumb, you should never remain stationary. The Pr. 123bis doesn't have any armour, and all other boats at its battle rating can kill it, so to make it much more difficult for the opponents, try to stay at your top speed and avoid head-on encounters. Although, you can still handle some threats from the sides because your guns' rotation speeds are very fast.

==== '''Development''' ====

In 1960, work was started to upgrade the M60 main battle tank, as the T95 project and the project to create composite armor ended. The prototypes fitted the T95E7 turret on the hull of the M60. In order to increase the room in the turret for the crew the gun used the M140 mount, which moved the gun forward 5 inches. The first two prototypes (Pilot 1 and 2) were ready in May 1961, and the third prototype (Pilot 3) was ready in June 1961. The prototypes were designated as the M60E1, and they were all built by Chrysler Defense. Pilot 1 was tested at Eglin Air Force Base, Pilot 2 was tested at Yuma Test Station, and Pilot 3 was tested at Fort Knox. The M60E1 was accepted for American service on 22 October 1962. The designation for production M60E1 tanks was Tank, Combat, Full Tracked: 105-mm Gun, M60A1. Production began on 13 October 1962, with an order of 720 units by the Army.

The upper glacis armor of the hull was upgraded from 3.67 inches to 4.29 inches at 65°. The steering wheel was replaced with a T-bar control, and the break and accelerator pedals were rearranged for easier usage by the driver. The tank was upgraded to the Continental AVDS-1790-2A engine and the CD-850-5 cross drive transmission, and it used the T97 track assembly. The first return roller was moved slightly, and shock absorbers were added to the second road wheel pair. The addition of the shock absorbers was due to the increased weight of the armor and new M60A1 turret.

'''Turret'''

The main feature of the M60A1 was a new turret, which was the turret of the T95E7 medium tank prototype. The new turret had more armor protection, and it also could had more room for the crew, because of the new M140 gun mount. A fume extractor was added to the rear of the turret bustle, on the left side; this would prevent fumes and smoke from accumulating inside the vehicle when the weapons were fired. The loader and gunner received padded seats, replacing the wire mesh seats which were uncomfortable. Ammunition for the main gun was increased to 63 rounds, with 15 rounds in the turret bustle, several rounds in the turret ring, and the rest stored in the hull. The turret was equipped with a new traversing mechanism, and an AN/VSS-1(V)1 IR searchlight was fitted above the gun mantlet. It received the M19 FCS, which consisted of the M17A1 coincidence rangefinder, M10A1 ballistic drive, and the mechanical M19E1 ballistic computer for the gunner. The M60A1 tank uses the M68E1 105 mm gun. The M68E1 gun shared the same firing characteristics as the M68, but had several design improvements including an updated gun hydraulic configuration, a stabilization upgrade for the gun (but not a full stabilizer), a gun elevation kill switch for the loader, an improved ballistic drive, and other component refinements.

Description

GarageImage Pr.123-bis.jpg


The Pr.123-bis is a rank II Soviet motor torpedo boat with a battle rating of 2.3 (AB/RB/SB). It was introduced during Update 1.79 "Project X" when the Soviet fleet was implemented into the game.

General info

Survivability and armour

X-Ray view of the Pr. 123bis showing key components that are prone to be damaged when taking enemy fire.

The Pr. 123bis doesn't have any armour in the game. When under fire, it is almost certain that an opponent will disable your engines and/or set you on fire (see image on the right). However, you will very rarely be destroyed due to an ammunition explosion.

Mobility

The Pr. 123bis can reach speeds over 120 km/h in AB and around 90 km/h in RB and SB. Backwards, the Pr. 123bis can reach -45km/h, so there should be no trouble reaching strategic points first or at the same time as the lighter boats. The Pr. 123bis turns very quickly, a tactic which should be used to flank opponents and destroy them with machine guns. Lastly, it is unwise to come to a full stop, due to the fact the ship becomes a "sitting duck", easy to pick off by enemy ships or aircraft.

Armament

Primary armament

Main article: DShK (12.7 mm)

Primary armament composes of two, dual mounted DShK heavy machine gun turrets with one located at the stern and the other at the centre of the vessel just above and behind the bridge. Note that the turret at the stern is obstructed when pointed towards the bow due to the other turret therefore somewhat restricting fire coverage. The turret just behind the bridge has near 360° though it is slightly obstructed by the mast when pointing towards the bow.

The DShK 12.7 mm guns provide good firepower and rate of fire against similarly sized ships and somewhat larger ships thanks to its heavy calibre. They have an ammunition capacity of 1,000 rounds with reloads taking ~4.7 seconds. Available belts to research include the high explosive incendiary (HEI) and armour piercing incendiary tracer (APIT) rounds.

Torpedo armament

Main article: 45-36NU (450 mm)

The Pr. 123bis carries two 450 mm wet-heating 45-36NU torpedoes. They have a range of 3 km at a speed of 78 km/h or a range of 6 km at 73 km/h with the Torpedo Mode module installed. They are placed at the bow of the boat and fired out already at speed, so you can surprise your opponents with your torpedoes, unlike early American boats, which simply throw the torpedoes to their sides.

Be careful with your torpedoes! Due to torpedoes being fired out of their tubes at an upwards angle, this means that your torpedoes might over-shoot (literally) any boats which are passing right in front of the Pr. 123bis.

Special armament

Main article: BM-1 small depth charge

The Pr. 123bis can carry 6x BB-1 depth charges, which can be used as timed mines to damage/destroy tougher enemies. You can place depth charges around a capture point if you get there first, or in front of an enemy.

Remember to set your Depth Charge activation time before battle, if you carry depth charges. The default option of 3 seconds is too short to be useful, so it is advised to set it to something between 5-8 seconds to keep your options open.

Usage in battles

The Pr. 123bis is one of the first Russian boats that get decent firepower, which can destroy its opponents very quickly. Moreover, it gets two torpedoes, which are fired forwards at speed (can be an advantage, but also a disadvantage). All of that weaponry is placed on a motor boat which can reach very high speeds. It's a boat that will help you grind out USSR rank I fleet.

The Pr. 123bis strikes a balance between speed and weaponry. At its low battle rating, the two dual 12.7 mm machine guns reliably destroy all light boats, experiencing difficulty only in a full up-tier. For the most part, the Pr. 123bis should be used as a flanker. Your machine guns destroy compartments with 3-5 bursts, and if you get the first shot on most of your opponents, they are most likely going to die very soon after. However, if you meet tougher opponents, it is viable to simply cross the map around the flank, (ignoring the lighter boats) while the opponents are focused on their front, and fire your torpedoes at their sides (best done when up close and personal).

As a rule of thumb, you should never remain stationary. The Pr. 123bis doesn't have any armour, and all other boats at its battle rating can kill it, so to make it much more difficult for the opponents, try to stay at your top speed and avoid head-on encounters. Although, you can still handle some threats from the sides because your guns' rotation speeds are very fast.
