Fancy CIWS installations that can shoot down two objects before requiring a complicated multiple minute reload are basically useless versus drone swarms or even large rocket salvos. This is also assuming that the readiness reports weren't fully falsified and the CIWS were broken or unloaded, as the outpost in Jordan hit likely did not expect any action. Both the Army's extreme level of corrupt practices and braindead doctrine will get a lot of boys killed if this nonsense escalates into a full blown war with Iran.
