The Infanterie gevechtsvoertuig Stier (IgV, "Infantry Fighting Vehicle" Stier, "Bull") is a Doraltic Infantry fighting vehicle designed to supplement a previous lack in dedicated IFVs in the bourgeoning United Republics Defense Forces. They entered active service with the United Republics Army in 2006, with 630 vehicles ordered up to 2019. Other nations, including Serpens Land have additionally adopted the vehicle.

The Bull is built on an aluminum hull which carries a modular THD steel and titanium armor, which can be replaced in the field. The 8x8 wheel combination is designed to make the IgV more comfortable and less costly than a tracked vehicle, while giving it sufficient mobility to back the Lévesque tank they would serve beside. The Bull is also designed to be transportable by the C-5/10 Albrantoch, with an empty mass less than 18 tonnes (full load mass up to 28 tonnes), making it one of the only two present airmobile pieces of armor in the United Republics military, the second being the ageing Barracuda tank.

In the mid 1990s, the Stiuraian government started the MpV (Modulair pantservoertuig — Modular Armored Vehicle) program as a direct response to lessons learned from the Battle of Rippen and the broader scope of the First Arvannan War. It initially sought to create a relatively light and maneuverable armored vehicle capable of fighting in urban combat environments. It was the last government project initiated by the Second Stiuraian Republic before it acceded to the United Republics, which with the added resources of the new nation, put further focus on developing a worthy vehicle.

Production began in earnest in 1998 with South Alban Ironworks and the Giffardmeer Company both contributing to the early prototypes, the Untied Republics put in an order for nearly 700 vehicles on 16 June 1999, hopeful that the design could prove itself soon enough to replace the multinational arsenal the newly reunited nation found itself with. In through 2000 and 2001, the program reached some major milestones: The mobility/agility tests, the armor tests and the electronic systems tests were all successful, vindicating the vehicle enough that mass production at GC's Boissieux Plant would begin by mid-2001. Due to Baetylus, the program was put on pause after the electronics test for the rest of 2001, only restarting in 2003 when the first 5 prototypes (4 standard and 1 Command Post) were tested in real conditions. These tests proved some crucial design mistakes on the DRAGAR turret, which had to be redesigned for both the prototypes and any vehicle produced up to that point. The subsequent 2 years delay in the program between this and its eventual adoption are consequences of this design flaw and the following correction. During this time, a small fleet of 12 vehicles were delivered as part of a test batch to Serpens Land, allowing the Serpens Land Army to perform further tests on the vehicle in collaboration with the United Republics Army, accelerating the original program's completion.

As the development program reached completion in 2004, other variants were studied, focusing around broadening the vehicle's capabilities. A mortar version and a vehicle using the MILAN Missile were the first to be developed. It would be these four variants, as part of a wider multi-mission package, that would see official adoption by the United Republics Army in 2006, where it made the since modified 625 vehicle order. By 2011, a redesign of the frame allowed the vehicle to switch configurations on much shorter notice, a trait gained by studying the Alteran-produced L-46 Vortex. Further options for upgrades remain in consideration, as the United Republics continues to fund the IgV program at large. As of 2019, the Bull's production has shifted entirely into "Block 2" featuring the 2011 frame redesign and a 2014 update to the electronics suite.

As of 2019, the United Republics operates the largest fleet of IgVs, amounting over 630 across the Army, Marine Corps, and the Citizen's Guard, about one-third of which are Block 2 versions. In addition, the Serpens Land Army has ordered 150 vehicles, which has been fulfilled, several of which produced prior to the Block 2 redesigns are seeing various upgrades.
