Notes: This vehicle is meant to provide replacements for Singapore’s aging M-113 fleet, to provide a base vehicle for further expansion and vehicle types, and to provide an attractive product for export buyers. It is a heavily-armored APC that is highly survivable in most environments. The Bionix is amphibious with 5 minutes of preparation.

There are three APC variations of the Bionix. The Bionix 25 is armed with a 25mm Bushmaster autocannon, and has a commander’s and coaxial machinegun. There is also a machinegun near the rear roof hatch that may be aimed and fired from within the vehicle.

The Bionix 40/50 is the sister vehicle to the Bionix 25, used mainly in the assault role and for crowd control. The turret on this version is replaced with one mounting an M-2HB and a 40AGL grenade launcher. This is a one-man turret. The commander’s machinegun is deleted, as the commander also acts as the gunner.

The Bionix ICV is similar in armament to the Bionix 40/50, but the weapons are mounted in a remote weapons station with the crew member manning them inside the armor envelope of the vehicle. Though there is a hatch behind the gun station, he is not required to look out of it to effectively aim and fire the weapons. Armor is increased over other models, but the armor is modular and may be reduced down to normal Bionix hull armor levels.

Twilight 2000 Notes: These vehicles do not exist.

Notes: The Ultra modification consists of a standard M-113 chassis (usually, an M-113A3) with one of three turrets and with additional ceramic armor plates. The Ultra variant was specifically designed for urban warfare, and has appliqué armor added to all faces for extra protection, even the deck. Due to the amount of ammunition carried, the amount of passengers carried is much smaller than a standard M-113, so these vehicles were generally used for fire support of other APCs. Three turrets are possible: one the same as on the Bionix 40/50, one with an overhead mount carrying a 25mm autocannon and machinegun, and one that is the same as that turret, but with a TOW II launcher.
