Description
The luftvärnsrobotvagn (lvrbv) 701 is a Swedish self-propelled anti-aircraft vehicle equipped with a short-range RB 70 surface-to-air missile system designed and built in Sweden. The vehicle does not have NBC protection and does not have night vision capabilities. Except for the weaponry, the lvrbv 701 is identical to the pansarvärnsrobotbandvagn (pvrbv) 551 ATGM carrier. Both vehicles were constructed on the chassis of old infanterikanonvagn (ikv) 103 self-propelled guns (however, some pvrbv 551s were constructed on the ikv 102 chassis instead). A total of 49 units were built and were in limited service throughout their lifespan. The vehicle was decommissioned in the early 2000s.
Introduced in Update 1.97 "Viking Fury", the lvrbv 701 is a special self-propelled anti-aircraft vehicle with some capability to fight enemy ground vehicles. With the upgraded RB 70 Mark 2 surface-to-air missile's outstanding 200 mm armour penetration, this compact vehicle is capable of killing both lighter enemy ground targets and aircraft. Furthermore, the vehicle's low profile aids in stealth during engagements and allows players to hide behind low obstacles. However, the lvrbv 701 lacks a search radar, requiring players to manually locate enemy air targets with their eyes, resulting in low efficiency. Finally, due to the vehicle's limited elevation, players will have difficulty engaging hostile aircraft at high altitudes.
General info
First to introduce the SAM gameplay to Sweden, the Lvrbv 701 is a lightly armoured chassis identical to the Pvrbv 551, both being based on the much older Ikv 103. The design is simply a man-portable RBS 70 missile system placed inside the refurbished chassis. Due to this structure, the Lvrbv 701 features no radar to scan for incoming targets, and relies on a single missile salvo with a long interval between reloads. This, combined with bad traversal of the launcher, and low mobility, means that the Lvrbv 701 is forced to engage carefully, as it has no proper way of defending itself outside of getting the first jump.
Though to list its strengths, the Lvrbv 701 features a high agile and reliable missile system. The RB 70 is incredibly devastating to those that face it, as the SAM can easily damage unsuspecting enemy aircraft, since there is no radar to notify them of your presence. And thanks to the agility, the missile works comfortably at both closer and longer ranges.
Survivability and armour
Frontal armour on the Lvrbv 701 consists of 20 to 25 mm of rolled homogeneous armour. Ideally, this can provide 28 to 30 mm of effective protection which should stop most low calibre machine gun fire, as well as .50 cal machine guns.
Side armour on the Lvrbv 701 consists of 10 mm rolled homogeneous armour which, due to its limited angles, only affords protection against low calibre machine guns.
The turret has no armour whatsoever.
The crew of 4 consists of a driver, gunner, loader and commander all positioned closely together in the front half of the vehicle.
Overall, protection on the Lvrbv 701 isn't spectacular and with a compact crew placement, including an exposed gunner, a simple burst of machine-gun fire from a .50 cal or larger fired at the sides or top can leave you knocked out. Its low profile and compact size does, however, work in your favour and lets you hide from most other ground vehicles and any aircraft/helicopters that haven't spotted you launching a missile.

General
The Lvrbv 701 is difficult to get used to, as the high BR ensures a punishing top-tier environment. Since the Lvrbv 701 is meant for anti-air operation, the targets above you are usually easy pickings. The main threat for the Lvrbv 701 is instead ground vehicles, as the tank has almost no way to defend itself against such opponents. The ideal way to play the vehicle is to stick close to your allied tanks, as they can deal with the ground threats for you, while you keep the airspace safe. The Lvrbv 701 feature scouting, and can easily aid teammates that need information about enemy positions, or need to be repaired.
Engaging air targets
When the Lvrbv 701 spots an air target, it's important to think about what you're engaging. Helicopters such as the Ka-50, can easily see the missile coming, and are usually expecting some sort of retaliation for launching missiles away from the battlefield. A tip is not to attempt to lock such targets, and instead estimate the distance, and launch it when they're busy. When fighting helicopters at close range, such as the AH-1G, or Mi-28N, it is important to launch as soon as possible, and destroy them before they get above you, as you have no ability to destroy them at point-blank distance.
Aircraft are slightly more difficult to destroy, as the RB 70 missile lacks significant velocity compared to other systems. Instead, the manoeuvrability of the missile comes to a lot of help as planes will struggle to avoid it while manoeuvring. When first engaging an aircraft, knowing if it has RWR is critical, as aircraft aware of you might go for another pass or even worse strafe you from a blind spot. The missile works best when attacking at medium range, where the aircraft is either approaching or flying parallel to your position. Aircraft are usually easy to shoot down, but should always be engaged with consideration, as your reload leaves you vulnerable to counter-attacks from the same opponent.

The Lvrbv 701 can be used to engage light vehicles, as the later missile has a lot of penetration. But engaging has to be done with caution due to the slow reload! |
Pros and cons
Pros:
- RB 70 Mk.2 missiles have 200 mm of penetration which can be useful against light ground targets
- Small vehicle profile allows you to hide behind cover effectively
- Unarmoured turret can help in reducing the visibility of the vehicle behind cover
- Smoke grenades can help when getting strafed by aircraft
- Upgraded RB 70 Mk.2 missiles are only a Tier II modification
- Can use the scouting mechanic to tag enemies and also help repair teammates
Cons:
- No secondary armament
- No search radar, only a tracking radar meaning you have to manually find targets
- Relatively sluggish turret rotation speed makes acquiring fast low flying targets difficult
- Only 200° total (±100°) of missile launcher rotation
- Max elevation of 35° makes tracking high altitude targets pretty much impossible
- Average mobility with very slow reverse speed
- Unarmoured turret leaves the gunner very vulnerable to knockouts
History
In 1983, the Swedish military gave a contract to Hägglunds and Söner to convert Ikv 102 and Ikv 103 vehicles into Lvrbv 701 surface-to-air missile carriers. The Ikv 102 and Ikv 103, infantry support vehicles mounting a 105 mm gun, had become obsolete in the past few years. At the same time, the same companies were contracted to convert Ikv 102 and Ikv 103 vehicles into Pvrbv 551 anti-tank missile carriers. The hull of the Ikv 102/Ikv 103 was plated over, in order to extend the crew compartment the full length of the vehicle. The engine was replaced by a Ford V-6 engine. The armament consisted of a RBS 70 surface-to-air missile launcher in the center of the hull, which was raised up through a circular opening in the roof of the vehicle - covered by a two piece hatch - in order to fire the weapon.
