20mm TCM-20

Notes: This light AAA gun is basically an old US M-55 trailer-mounted AA machinegun system with the four M-2HB replaced by two HS-404 20mm autocannons that have been modified to fire more powerful HS-804 ammunition. The resulting gun can be used from a trailer, fixed position, or most light armored vehicles. Each autocannon is fed from 60-round drum magazine, but the guns must be cocked manually when reloaded.

23mm TCM Mk 3

Notes: Using captured 23mm autocannons, the Israelis also produced a version of the TCM-20 with ZU-23 autocannons. This system was used for a short time by the Israelis, but they later took them out of service, replacing them with more TCM-20s. Rumors point to Chile and South Africa as possible recipients of some of the cast-off TCM Mk 3s, but this is not confirmed.

Twilight 2000 Notes: The Israelis kept some 75 TCM Mk 3s, using them for home defense. South Africa and Chile also received some.

Merc 2000 Notes: As Twilight 2000 Notes, but the Israelis did not keep any.
