https://prnt.sc/jexki2Please reword the missile silo description to make it clearer.
Perhaps (add in bold):
Immobile defensive structures are an easy target for attack. Special missiles were designed long ago for interplanetary attacks on such targets. Missile silo is designed to store both offensive Interplanetary missiles and defensive anti-ballistic missiles. Each anti-ballistic missile takes one slot in the silo, and each interplanetary missile takes two slots in the silo. With each level of the silo, five interplanetary missiles or ten anti-ballistic missiles can be stored, silo must be at level two to start building missiles. Storage of both Interplanetary missiles and anti-ballistic missiles in the same silo is allowed. Cannot be destroyed by Lexx.
