General info

The Char de bataille B1 ter in the garage.

The Char de bataille B1 ter (Battle tank B1 "final") is a gift Rank II French heavy tank with a battle rating of 2.3 (AB/RB/SB). It was introduced in Update 1.75 "La Résistance". With the best armour at its BR, this tank is a beast in long-range engagements since it is hard to penetrate at distances. While not having the best armament, it should do the job taking care of these dangerous early SPGs and light tanks. The "ter" suffix to its name is an abbreviation for the french word "terminal" which means "final". Its most noticeable features from its predecessor (B1 bis) are an increased horizontal traverse for the hull gun, thicker armour and an extra crew member.

The main purpose, usage and tactics recommendations

General play style

The Char B1, upon playing it for the first time will be slow in both acceleration, max speed and turret rotation speed. The Hull gun is usable, while not being very suitable for this tank's main role. The best way to play the B1 ter is to hold down a position, preferably hull down (as its turret is thick and small, it will ricochet most shots it will take). Playing the B1 ter rightly, there is only 3 ways to get killed:

  • Being outflanked by a light tank
  • The enemy has been lucky enough to get a shot through a shot trap
  • Meeting a dangerous gun (see Specific enemies worth noting)

Vehicle characteristics

Mobility:

This tank's mobility won't allow you to position fast enough. Taking time is the only way to get where you want safely. Since this tank is pretty long and narrow, do not engage in cramped spaces since you will not be allowed to manoeuvre as you wish. You reverse speed won't allow you to retreat if things get bad around you, stay behind the front-lines, making good use of your armour.

Armour:

In order to effectively use this tank's armour, there is a few things to consider. First of all, there is some shot traps,most noticeably the turret ring and the hull gun mount. In order to minimize your enemies' chance to hit these weak spots, stay away from them. Second, even if your armour is very strong for the BR, do not completely rely on it by sitting around in an open field: you will eventually get hit where it hurts. The third thing to consider is your small and thick turret: hide that big clumsy hull behind a hill and pop out only your hard "head", take a shot, fall back, reload, repeat. If something goes wrong (i.e. getting shot in the turret ring), there is usually enough men left to take the job left by their dead "camarade". Do not bother getting spotted: it is your job to stay in the enemies' sights while your lighter teammates do what they ought to. In some situations, it can even be used as a breakthrough tank, rely on your own experience to guess when it is time to do so.

Firepower:

With the same gun as most other rank 2 French tanks, the B1 ter will never be recognized for having a fearsome armament: penetration rates are even lower than most reserve tanks while reload time is twice as long (a known feature of early French tanks). The turreted armament is only good at firing light targets such as SPGs and light tanks. Elevation and depression angles are amazing but turret sewing rate is a bit slow: this tank has been designed to be hull-down. As for the hull-mounted gun, it should only be used as a close range defence device, as it has poor penetration rates and high drop. Exposing your hull-mounted gun for long range engagements does not only makes you vulnerable, it is also mostly ineffective.

Tactics

Specific enemies worth noting

All light tanks are dangerous as they can easily outflank you if they get too close, shoot them down before it happens. Also, do not engage medium and heavy tanks from the front as it is only a waste of efforts.

With that aside, such heavy armour is hard to get through from the front but some enemies may still pose a threat. Here is a list of big guns you may encounter at this BR spread:

Counter-tactics

Due to the extremely heavy frontal armor, one should try to use mobility to flank the B1. However, if that isn't possible, you'll want to try and hit the "mailslot" of the turret ring. It may be a tricky shot, but there's only ~40 mm of armor there. When flanking ,it is preferable to go for the right side of the tank as is is filled with ammo and fuel.

Pros and cons

Pros:

  • Overall good armour
  • Very heavy frontal armour for its rank.
  • Strong turret from the front
  • Good at side-scraping (thick sides)
  • Nearly impenetrable hull when angled
  • Increased armour values all around from its predecessor (70 mm instead of 60 mm)
  • Extra crew member
  • Smaller turret ring than its predecessor
  • No more weak "grille" and sides are no longer completely flat
  • Top part of tracks is now shielded
  • Decent firepower
  • One of the best in-game depression (-18°, turret gun)
  • Has 2 main armaments
  • A rare feature on French tanks: it has APHE ammunition.
  • MAC 31 coaxial MG
  • Turret gun has LOCK, which makes stop-and-shoot tactics effective.
  • Hull gun has better horizontal traverse than its bis version.
  • Carries more ammo than the bis

Cons:

  • Armour has many shot traps, easing the ask of killing it
  • Engine grille on left side is a 15 mm weak point, nullifies angling from this side.
  • Fuel tank behind the grille lights up very often when penetrated.
  • Large turret ring is weak (25-40 mm poorly sloped)
  • Hull gun mount is a weak spot and can be penetrated by most guns of the tier.
  • Crew is cramped
  • Turret rear plate is only 38 mm thick
  • Has a tall and "thin" cupola
  • Literally has an hallway full of ammo in the back
  • 8 mm grille above ammo and loader makes it vulnerable to aircraft HMG fire.
  • Guns feel lacking
  • Lacking penetration from both of its guns
  • Abysmal traverse on 75 mm gun (~1° left to right)
  • Slow reload on both guns
  • Only stock ammo choices
  • APHE shell won't detonate when shooting at light targets (25 mm or less armour)
  • Hull gun is hard to master (not beginner-friendly)
  • Mobility is sub par
  • Not very mobile due to weight.
  • Slow hull turning rate
  • Reverse speed is low (-3km/h)
  • Turret sewing rate is slower than its predecessor
  • 4 tons heavier than its predecessor while sharing its engine.
  • Has a very noticeable and thick antenna sticking upwards.
