Apparently, the UEF defeat has not struck all UEF commanders with the same appropriate sense of dignity, humility and respect for their Aeon overlords. Either that or their morale has collapsed to such an extent that their aim is really, really REALLY off.
Or at least, that seems to be the only logical conclusion from observing a UEF ally "accidentally" sniping not the Cybran, but the Aeon commander on planet 14 recently. To be fair, the UEF commander immediately saw his mistake and withdrew from the battle entirely, to prevent further mishaps. Unfortunately, that left the battelfield to the Cybran commander, who was probably as perplexed at the development as anyone else.
