Description

The Stridsvagn m/40L is a rank I Swedish light tank with a battle rating of 2.0 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury".

General info

Survivability and armour

The Strv m/40L is essentially the Strv m/38 with increased frontal armour. The frontal hull armour is increased to a maximum of 43 mm, while the turret is uparmoured to 50 mm. This provides a decent degree of protection against autocannons and heavy machine guns as well as low calibre anti-tank guns. However, the rest of the tank's armour profile remains identical (13 mm), and it is thus still very vulnerable from directions other than the front.

Armour	Front (Slope angle)	Sides	Rear	Roof
Hull	13 mm (58°) + 30 mm (46°-58°) Upper glacis 13 mm (45°) Lower glacis 13 mm (30°) + 35 mm (29°) Upper plate 13 mm + 35 mm Driver's cupola	13 mm	13 mm (33°) Lower 9 + 15 mm (14°) Upper	4-13 mm
Turret	15 mm + 35 mm (14°) Turret front 15 mm + 35 mm (9°-72°) Gun mantlet	13 mm	13 mm	5-8 mm

The engine of the Strv m/40L is identical to that on the Strv m/38. However, the tank is considerably heavier due to the increased armour, thus somewhat worsening its acceleration. Mobility characteristics are otherwise almost identical to its predecessor.

Armaments

Main armament

The Strv m/40L uses the same 3,7 cm kan m/38 gun as the Strv m/38. The turret mounting has been modified, however, to provide an even greater amount of gun depression (15°). The ammunition choice is identical: it starts with the unremarkable slpprj m/38 APBC shot. At tier IV, the slpgr m/39 APBC and slpprj m/49 APDS rounds can be unlocked. The former round has a small explosive filler while having only slightly less penetration than the stock APBC shot. The APDS round has over 100 mm of penetration at close range and a muzzle velocity of 1,150 m/s and is capable of penetrating anything the Strv m/40L is likely to face. The high velocity makes it good for sniping, but the APDS round tends to be less accurate than the APBC rounds.

It should be noted that if the "Camera from tank gunner sight" option is enabled, there is a protrusion in front of the gunner's sight that can block part of the gunner's sight view when depressing the gun.

Usage in battles

The Strv m/40L is a light tank, that got a large bite for its small caliber, being armed with a 37mm Bofors gun doesn't seem like a big threat to most tanks at 2.0 since most light tanks and some medium tanks like Pz.III E are equipped with a 37mm gun. Compared to most other tanks at that battle rating the Strv m/40L is able to research APDS rounds.

The Strv m/40L excels in hull-down combat where it can exploit its outstanding gun depression and relatively good rounded turret armour. The powerful APDS round allows it to easily penetrate and disable even the heaviest of tanks it can normally encounter, such as the B1 bis and Valentine. However, it has relatively low post-penetration effects, and will often require multiple shots to kill larger tanks due to the larger crew compartments making its small 37mm a deadly force to be reckoned with. But the tank's mobility is quite respectable and allows it to keep up with other medium tanks and making it able to move around the battlefield with ease and not only fight with hull down position but also bring the fight to the enemy side. The frontal armour is quite good, but quite thin elsewhere making it vurnerable to side shots and rear shots so best to always point the frontal armour towards the target.

Strv m/40L might have alot of positivity to it but there is also negative sides, until it get researched APDS round it have to deal with using the APCB rounds Slpprj m/38 and Slpgr m/39 which got between 59-55mm penetration at 10m forcing it to be up close and personal tank till it unlocks the APDS round where it can penetrate the enemy tanks from further distances, though the APDS is not hitting accuratly at long distances, making it mostly useful at medium range to close range to be fully effective round. Tank's mobility was also respectable but in terms of revers the Strv m/40L is lacking the means to reverse away out of danger, making it better for it to turn around fast and drive back into cover. Though doing that exposes the Strv m/40L's weak side armour and possibly the rear armour which will be a good chance for the enemy to knock it out with ease.

Strv m/40L got enemies to be aware of tanks like M4A3 (105), Pz.IV E and StuG III A got HEAT rounds that will easily knock out the Strv m/40L with the crew compartment being so compact they can easily take out the 3 man crew with one shot making alot of these targets a priority enemy for the Strv m/40L. But target with large crew compartment and large crew like B1 ter, LVT and T-28E can also be a threat to the Strv m/40L having a lot of crew can make it hard for the Strv m/40L to knock them out fast, which makes the Strv m/40L forced to try knock out the enemy tanks gun and work down its crew one by one if necessary. But taking to long will expose it to be surrounded or outflanked by nearby enemies that will come to assist the target in need.

Pros and cons

Pros:

• Good frontal armour
• Access to an outstanding APDS round
• Good mobility
• Fast reload
• Excellent gun depression in combination with good turret armour makes it great at hull-down

Cons:

• APDS is somewhat inaccurate at long range and lacks post-penetration damage
• Very thin armour other than on the front
• Poor reverse speed
• APDS is tier IV modification, and without it you have to shoot terrible AP shell with 59 mm of max penetration and low post-pen damage

History

In 1934, a new light tank was designed for Sweden by Landsverk, the L-60. It was based on the Landsverk L-10/Strv m/31, but with a new torsion bar suspension system. The torsion bar suspension system was a large improvement over the Christie suspension system. The L-60 S/1 entered service with the Swedish military in 1938 as the Strv m/38. The L-60 S/1 Strv m/38 was armed with a Bofors 37 mm gun. In 1939, Sweden ordered an improved version of the Strv m/38. It was designated as the L-60 S/II Strv m/39. The Strv m/39 was armed with an improved Bofors 37 mm gun and had a new engine. During World War 2, the Strv m/39 was upgraded with additional armor welded onto the glacis and mantlet.

At the same time, there was a need for another upgrade of the Strv m/39. The turret mantlet was modified and a commander's cupola was added along with side hatches. These also received the upgraded armor of the Strv m/39, and were designated as L-60 S/III Strv m/40L. The L-60 served with the Swedish military throughout World War 2, and also became the basis of the L-62 Anti II SPAAG designed for Finland, which also saw service with Hungary as the 40M Nimrod. In 1960, 20 L-60 tanks were sold to the Dominican Republic by Sweden. Rebels, backed by the US Marine Corps, fought against the L-60 during the Dominican Civil War. 3 were destroyed by M48 Patton III's, M50 Ontos, and anti-tank fire. 12 were upgraded and saw service until 2002.
