Sannsystems Grethe

The Sannsystems Grethe, also called Grethe Mobile Gun System, is an 8x8 wheeled mobile gun system, developed and manufactured by the sannlig state-owned military contractor Sannsystems AB, respectively its subdivision for amoured and land systems, S²Armours. It was developed for the Shenewan Imperial Army, who wanted a system able to keep up with Villhund II and Buffalo equipped formations but still able to bring large-calibre firepower to bear. Initially, two variants were to be procured, one equipped with a 90mm gun for use in reconnaissance regiments and one with a 123mm gun for use in tank destroyer regiments. However, a combination of budgetary constraints and a judgement that 90mm guns would not carry sufficient extra ammunition for their reduced capability to be offset led to all vehicles being procured with 123mm guns. At Shenewan request, the vehicle shared a number of parts with the Villhund II. Because of the similarities in its design, the development of the Grethe informed many decisions later made when designing the Villhund III, meaning it has a certain degree of commonality with both the Villhund II and Villhund III. The turret's design was largely based off and informed by the Løve 1 turret.

Armour
The Grethe's baseline armour offers all-round protection against 14.5mm rounds and limited protection against 25mm rounds on the frontal arc. This protection can be increased to offer limited protection against 30mm rounds with add-on armour.

Armament
The Grethe uses a 123mm gun, whose design informed many of the choices made when integrating it onto the Løve 2 family of tanks. It can carry 39 rounds for this gun, 12 ready in the turret and 27 in the hull. It is able to fire all natures of ammunition used in Sannlig tanks, although due to its being a smoothbore gun rather than rifled, the performance of rounds is not equal between the two.

The Grethe also carries two 7.62 GPMGs, one coaxial and the other pintle mounted. The vehicle can carry up 4,000 rounds of 7.62 ammunition.

Grethe 90
A variant of the Grethe which used a 90mm gun.

Grethe 123
The Grethe variant adopted by the Shenewan Imperial Army.

Grethe 123M
A modernisation of the Grethe 123, developed privately by Sannsystems AB. It features an autoloader, reducing the crew requirements from 4 to 3, and improved armour, including an active protection system. It also modernises much of the vehicle, replacing parts common with the Villhund II with parts common with the Villhund III.

Grethe 123M1
The Grethe 123M1 is an even further modernised variant, being fitted to the operational requirements of the sannlig forces. It shares a lot of parts with the Villhund XP³ and serves along the Heavy Companies in the sannlig cavalry units.
