Walrus and its variants tend to have decent armour and mobility, along with below-average output. With the combination of agility and toughness, the wanzer model proves to be of value in the frontline as melee or assault units. As seen in Front Mission 2, it was deployed heavily by Alordesh military, mainly as melee and assault units. In later installments, the O.C.U. Army in Huffman Island and Cambodian troops were also seen employing the model primarily as assault units.
It also have a branch series known as Strife, which has anti-piercing armours.
