I have absolutely NO idea if this is as intended or not, but here goes..
AI translocators, if there are no other player mobile units in-sector, will attack forcefields, translocating them to the far corners of the map. This, as you can imagine, strikes me as a tad unbalanced..
A single translocator can effectively nullify a MKIII forcefield in this way, opening up the command centre, turret-ball, or whatever else you have lurking under it to attack, often leading to the loss of a sector or capturable.
