The idea of a command field is just to facilitate the action so that pilots can spend more time crisis managing around the map and fighting each other rather than having:
YOU! Soldier A, Attack!
YOU! Soldier B, Attack!
YOU Soldier C, Attack!
YOU Soldier D, Attack!
YOU Soldier.... cough... hacking cough...
And you know what, the idea of remote command and control seemed like a great idea to many of the factions pre-war, right up until the point their codes were hacked through and units turned against them in a fraction of a millisecond.
The onboard quantum crypto descramblers of even the cheapest AirMech will make quick work of any wireless command and control system you can concoct. Those who have tried always end up paying dearly on the battlefield.
Time and war have shown that an exchanged command pellet, physically exchanged through contact, is the only reliable way to get your 'just in time nano fabricated death machines' pointed and going in the right direction.
And even with the pellet being clad in a tungsten alloy Faraday cage, Airmechs like the saucer can override and repurpose the onboard execution systems given enough time and proximity.
So, no, we'll be sticking with the combat protocol specifications as they stand, to keep our Goliaths and defenses from forgetting who their masters are.
