The T3 strategic missile defense, SMD for short, are stationary structures launching ordinance to defeat incoming ICBMs directed towards the protected area.
SMDs are built in the same fashion as the SMLs, with both launcher and ammunition to be built. Once loaded, Defense Missiles are launched automatically as soon as a nuke enters range, however it still must be reloaded after use. Nukes, launched by the player or allies, will not be targeted.
Counter-nukes are visible on the map, abeit no audio cue, shown as a red no-entry symbol; notifiing the attacking commander that the target has active anti-nukes in the area.
It is a valuable defense if you're expecting heavy use of nuclear armaments and because SMDs are built and loaded faster than SMLs, alert ACUs may often so-called nuke-proof their bases. Furthermore, base size should be considered with building more than one SMDs, so that their range can cover the expanse of the facility; Preventing a shrewd commander from landing a precise strike on outlaying buildings.
