Notes: The Sentinel is a twin 30mm autocannon system using Mauser Model F guns on a mobile field mounting. The trailer includes its own 40 kW generator, sufficient to power the unit. The unit also includes a laser rangefinder with ballistic computer and a passive IR night vision device.

Twilight 2000 Notes: This system is rare in the extreme, and usually not found outside of Italian units.

Notes: This is basically a Bofors L/70 antiaircraft gun carriage license-produced by OTOBreda in Italy and given a few improvements. The improvements include increasing the ROF from 240 rounds per minute to 300 (this has no practical game effect); the ability to fire newer forms of ammunition such as PFHE and 3P rounds; a larger magazine; and the ability to use batteries when a generator is not available. The 40mm AAG can also be attached to a remote control mechanism to place large numbers of guns under the control of a single gunner.

Notes: This is a field mounting of a popular Italian naval antiaircraft mounting using twin Bofors L/70 autocannons. The guns are linked together so that they recoil and fire at the same time; this increases the recoiling mass and thus lowers the recoil forces on the mount. The system can be linked to a Flycatcher air defense radar to form a system known as the Guardian. It can be further integrated into existing surface-to-air missile defenses. Each gun can be fed from 4-round clips through hatches in the sides of the cupola; the ammunition is held in magazines under the gun. The gun holds a total of 111 clips of ammunition. The entire cupola has an armor value of 2.

Notes: This is a modernized version of the Twin 40L70 above. The biggest combat modifications are improvements that allow the ROF of each gun to be quickened to nearly 500 rounds per minute each. Other improvements include computer-aided aiming, reduction in recoil length, larger side hatches, and a widespread use of titanium to increase strength of the gun components.

Twilight 2000 Notes: This weapon system does not exist.

Merc 2000 Notes: The Twin Fast Forty development is complete, awaiting orders that have not yet been placed.

Notes: This is an Italian autocannon designed for antiaircraft use, but made with ammunition to give it some antiarmor capability. It is primarily found on the Otomatic self-propelled antiaircraft gun and shipboard mounts.
