I remember a few years back I joined a FB GV fun run mission to take a Bish base, dont remember how deep the base was but it took and hour or so to get there in a M8. When we got into town and started hitting it, a Rook mission started to hit the base and furball over the base, we dropped town very quietly and snagged the base out from under them.... it was funny as heck to see the auto ack pop up and wipe them all out in seconds.
SAPP ran a few and held the base for a bit. Some great battles doing that.
