The enemy pilot is barely conscious but you drag him from his mechadroid and manage to bring him around. Interrogation isn't too difficult, just a matter of applying pressure to his broken limbs, his piercing screams however are sure to draw attention so you have to be quick.
He divulges that there are indeed more mechadroids around the facility but that this attack was just meant to hamper your military's responses while the real force moved on the city - even though you survived the ambush, your mechadroid is damaged and you present no threat.
You press for more information but he spits in your face "Harvester scum, I won't betray Commander Jargon!" at that he clenches his teeth together and within moments is foaming at the mouth having swallowed a suicide pill.
So there are more mechadroids nearby and they may have been alerted by his screams, you could still try searching the facility or you could head to the city and try to raise a defence. Alternatively you could try scouting for the main Stoner forces, perhaps you'll get lucky.
