His small smile turned into a frown as he set the skimmer down and surveyed the greenery between him and the bunker's personnel entrance. According to the fragmentary records Ursula Central had been able to reconstruct, the Bolo's first (and only) commander had been a Major Marina Stavrakas. He hadn't been able to find much on her-only that she'd been an R amp;D specialist, born in the city of Athens on Old Earth itself, and that she'd been forty-six years old when she was assigned here. R amp;D types seldom drew field command slots, which suggested she'd been grabbed in a hurry for the Bolo's emergency deployment, but experienced field officer or no, she must have been insane to leave a Bolo permanently on Stand-By. Either that, or, like Commander Albright, she'd died unexpectedly and been unable to change the settings. Either way, a Bolo as old as this was nothing to have sitting around in that mode.

Before the improved autonomous discretionary command circuitry that had come on-line with the Mark XXIV, Bolos had a hard time differentiating between "unauthorized" and "hostile" when someone entered their command areas. They'd been self-aware ever since the old Mark XX, but their psychotronics had been hedged around with so many safeguards that they were effectively limited to battlefield analysis and response. From the beginning, some critics had argued that the inhibitory software and hardwired security features had reduced the Bolos' potential effectiveness by a significant margin, yet the logic behind the original safety measures had been persuasive.

The crudity of the initial psychodynamic technology had meant the early self-aware Bolos possessed fairly "bloodthirsty" personalities, and the human technophobia an ancient pre-space writer had dubbed "the Frankenstein Complex" had shaped their programming.
