Survivability and armour
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.

Armaments
Main armament
The Rbs 55 is the same ATGM launcher found on the UDES 33 but gets access to better munitions. The reload time is the same as the UDES so enemies will be able to replace their crew member quicker than your reload. It also gets less ammo, carrying only 8 rounds instead of 10. It is recommended to take a full ammo load as you will definitely run low during an extended battle. The firing angles are more restricted vertically, with only -13° compared to the UDES' -20°. It is horizontally restricted to the 4 o'clock right and 8 o'clock left positions.
However, there is one big upgrade this launcher gets compared to the UDES; the ammunition. It starts off with the potent RB 55B (I-TOW) but can upgrade to the deadly RB 55C (TOW-2). The RB 55B is a good stock munition, being able to penetrate most, if not all, vehicles it faces within its BR range. However, the RB 55C is one of the best ATGMs at its BR range. With 800 mm of penetration, it has the ability to penetrate all vehicles at its BR and more. The slightly higher velocity makes it easier to hit long range targets before they can potentially drive into cover. It's also a Tier II modification so it can be unlocked relatively fast. This makes the launcher one of the most dangerous weapons to face at any range, provided the operator can stay alive, as the gunner is exposed from the waist up on the vehicle.

Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- RB 55B (I-TOW) is a potent stock ATGM, penetrating 630 mm of armour
- Comes with a stock 66 mm smoke grenade launcher
- The upgraded RB 55C (TOW-2) is a Tier II upgrade in modifications
- RB 55C penetrates 800 mm of armour and a faster velocity of 329 m/s
- Researchable Night Vision Device
Cons:
- Has virtually no armour, any heavy calibre machine gun can penetrate it from the front or side
- Gunner is exposed to artillery, aircraft strafing and machine gun fire
- Mediocre mobility, slower than most MBTs
- Less gun depression than its predecessor, UDES 33 (-13° instead of -20°)
- Inherits the same Horizontal Guidance problem with its predecessor (only able to rotate the launcher to a certain angle)
- Vulnerable while firing the launcher
History
In 1983, the Swedish military gave a contract to Hägglunds and Söner to convert Ikv 102 and Ikv 103 vehicles into Pvrbv 551 anti-tank 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 Lvrbv 701 surface-to-air 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 TOW ATGM 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. 55 Pvrbv 551 vehicles were delivered to the Swedish military.
Devblog
During the 1970's, the Swedish military came to realize that their anti-tank and anti-air regiments within the armored branch were substantially lacking in mobility and protection. As a result, studies were initiated in an effort to find potential solutions to this problem.
During the conducted studies, it was found that the previously decommissioned Ikv 102 and 103 SPG's could relatively easily be converted into mobile ATGM and SAM platforms. This sparked the development of several projects in the late 1970's, all of which aimed to convert the old chassis into modern missile carriers.
By the early 1980's, the viability of this undertaking had already successfully been proven through the creation of several prototypes. However, the decision was then made to not simply convert the old chassis, but to substantially rebuild them in order to facilitate necessary improvements.
By the mid 1980's, the work was considered complete and two new vehicles were developed as a result - the Pvrbv 551 and Lvrbv 701 - the former being the ATGM carrier, whereas the latter represented the SAM variant. Both vehicles subsequently entered service with the Swedish military in the mid to late 1980's.
In total, 57 Ikv 103s were converted into the Pvrbv 551 missile carriers, which served with the Swedish military from 1984 until 2000, when the last of the operational units was retired from service.
