At Drake's order, Kirin wheels the tank to the side of the road. Out of sight, but only from far away. Leaving the engine idling, she clambers out of the Bastion, already retrieving a block of C4 from her pack. She plants it on the side of the road, a few meters ahead of the Bastion, and sticks a blasting cap into the malleable explosive. That done, she covers it in fist-sized rocks and fragments of rubble; when she triggers it, the explosion would send the rubble outwards, like a fragmentation grenade on a somewhat larger scale.

She checks her detonator, confirming that the remote blasting cap is linked up with it. C4 was a stable explosive, and it won't detonate until she pulls the trigger. Plus, if it doesn't get used, it's less hair-raising to recover than a land mine. With her impromptu trap set up, Saki returns to the Bastion.
