Bonus 1
On board the APC is the pilot's family. One of them, a young boy, relates to you a story of when he was exploring a nearby cave. Deep into the cave he says he found an ancient Battlemech, but nobody believes him. Dispatching your salvage team (since the Clan forces egressed the area and the drowned Clan Mech is beyond the capabilities of your salvage team in the time available), they find that the kid is telling the truth. Deep in the dry cavern you find a BEL-1X Bellerophon.

Bonus 2
Alongside the Mech there are several crates, with unintelligible labels. Cracking them open, your team finds several spare parts, possibly intended to keep this ancient machine running, and even somewhat upgrade it from its Primitive status. You recover:
x1 Pitban 240 XL fusion engine, circa 2760 (no heat sinks)
x2 lower leg, x2 Foot Actuators for a 60-ton Mech
x1 60-ton Mech Sensors
Several sub-containers of various myomer lubricants, cooling hoses, and so forth. (Enough has survived to offset maintenance costs on 1 standard Mech for 1 month)
