The self-propelled artillery has been delivered, but the missiles have not yet arrived. Both Gao Yang and Polovich felt that it was too risky because the two batches of missiles were of the same model and delivered just two days apart, with chassis numbers and missile batch numbers being so similar, the risk of exposure was too great.
Therefore, under the pressure of the Iranians, Polovich sent the self-propelled artillery first. As for the missiles, Satan's manpower was only sufficient to operate two sets at the moment, more would be of no use.
The Iranians never had their hands on the first batch of missiles. When Satan decided to fire them, it would be impossible to compare the two batches of missiles, and only then would Polovich deliver the new missiles.
