Hmm, well I don't think that a Covenant AI would be a real problem, because human constructs are way superior to the Covenant's; Cortana wouldn't be horribly troubled to open a hangar door. The reason could more likely be they don't have those troops to spare to back up the chief, and another is how long it would take for reinforcements to arrive. It's not like there is a pelican just outside waiting for the call, right?
Also, if you could keep calling in reinforcements, that would seriously alter the gameplay.
