I have a single unit mobile vehicle, "SSM Bn" assigned on a mission to land strike 3 targets: FOB Serpent, Harpy, Hydra.
ToT is set.

Expectation: missile launch is timed so that each target is impacted at the ToT. This is indeed what happens if a single target is selected [or if multiple units where available].
Actual: all missiles are launched at the same time resulting in only a single target being properly hit at the ToT.
