Alvis Stalwart Mk.1 equipped with Swingfire missiles.
After the success of the FV600 series, Alvis Ltd. decided to develop a new vehicle, which at that time had no equivalents. A high mobility, cross-country, load carrier with capability to carry a 5 ton payload. The vehicle was named: Stalwart.
(But crew usually called it Stally or Stolly)
History
Spoiler
The first prototype of the Stalwart (named PV1) was done in 1959. It was made as cheaply as possible, to prove the concept that FVRDE’s punt hull design could be used as a 5 ton load carrier. British Army trialled PV1, and as they had been conducting trials with fording the FV603 Alvis Saracen, they asked Alvis if Stalwart could also ford.
Stolly PV1 wasn’t ready for fording trials and even wasn’t developed to be amphibious. Instead of swimming, it scooped up some water. After that Alvis Ltd. decided that next versions of the Stalwart should be amphibious.
The trials proved that the concept of a highly mobile all-terrain vehicle with a load capacity of 5 tons works. It was the signal for further developments, which led to the adoption of the Stalwart Mk.1 by the British Army.
(Some of the Stolly was also adopted by the Sweden army)
Although Stalwart first appeared as a load carrier, it also had to perform other important roles.
Such as:
Pathfinder (Winch assisted exit - with a rocket propelled anchor),
Ranger (Anti personnel mine dispenser),
Unit Bulk Refuelling Equipment.
In addition to them, there were also other versions that were not adopted into the service.
One of them was shown In 1964 at the Farnborough Air Show. It was Stalwart Mk.1 armed with the Swingfire ATGMs.
This Stolly has 4 containers, each of which has 4 Swingfire launchers. So that it has 16 ready to fire missiles and also 8 in the storage, and +24 if we take into consideration the “ammo box” game mechanic.
Only 48 Swingfire missiles 🤗
This ATGM is already represented in the game on the FV438 Swingfire and FV102 Striker. On the roof of the driver’s cabin Stally Swingfire has periscopic gunner’s sight, similar to the one on the FV438 Swingfire.

Swingfire gunner’s sight ^
But unlike the current in-game Swingfire type of the guidance, it should be MCLOS instead of SACLOS. (by the keyboard, not by the mouse)
Because only the late FV102 Striker was upgraded with the SACLOS guidance system.
The Stalwart’s cabin is covered in painted sheets of plywood to show how armoured Stalwart could be looking. Perhaps it’s something like BM-13N armored cabin
