"So first of all, the fact itself is that we're engaging the military infrastructure and military targets in occupied Crimea and the occupier’s infrastructure. If we're going deeper into strikes against the air defense system, it's more complicated here. First of all, the air defense systems themselves are very costly equipment and it takes a lot of time to produce those and Russian flags those systems because all this inventory is currently engaged in fighting against Ukraine and also in protection of Moscow. They've taken away air defenses from everywhere else. That is why, naturally, when we engage in another and another air defense battalion of the Russian military, they need to think about where they can pull those systems from and where are they able to tolerate less defenses in other places."
