Similar experiences to John. A RAAF Iroquois landed on some train tracks in the early 70s and the heel of one skid got stuck in the rails... and here come de train!! The crewy had run ahead to warn the train, but with all wheels locked up it skidded and skidded... and slid past the chopper on the next track! Lucky the pilot had turned the blade sideways.
Our Agusta was not an E, but we had some troubles landing on soft ground - the wheel sank into the grass, past the hub, and we were belly onto the ground. Lucky not to lose the antennas. It is possible to damage a brake line if it sinks too far.
We didn't leak too much oil - except from the dampers - but the Allison engines made sure the tail boom could never rust, being covered with a fuel residue and soot. The CG would progress backwards as the fuel burnt off from the front and the soot deposited at the back.
The Agusta was never a successful military machine, once the Russians developed an oil-seeking missile.
