Silencer is the ICBM nuclear missile silo. Built by all T2 land/air constructors it produces missiles that can hit anywhere on the map and turn whole bases and armies into ashes. It can be countered by anti-nukes within their limited range. Silencer has a bigger AoE than its ARM counterpart – Retaliator. In many situations it is even able to destroy two bases at once if they are built in vicinity.
Always make sure that your enemy is unaware of you building it, because anti-nukes are faster to build and load.
Stockpiling a nuke takes 180s, an anti-nuke – 90s. Few units may survive the nuke blast – Commanders, Banthas, Krogoths and heavier battleships. You can use EMP missiles or spy-bots to temporarily disable anti-nukes and strike uncovered areas.
