RC-Hangout

All look pretty far fetched to me.
The second one will just not work for sure.

I like the storage, loading and deployment aspect of the first two. The popup RPG is kind of a cool idea, but I'm not at all clear on how they supposedly embed so cleanly and completely into the ground. Maybe into a marsh or other soft soil, but sand, gravel, rock, and normal moisture dirt? They make bombs that embed but they require a great deal of mass and density, are subjected to huge G forces on contact, etc. All things that make it poor for holding sensitive electronics, mechanical bits, and explosives you don't want to go off soon after contact.

Third one is just goofy. How many high security locations can you just drive up to with an ATV and park while a drill embeds a popup RPG into the ground, and then have security kindly wave you away?

I do like the idea of a hanger rack to load up and deploy the munitions off the back end of a cargo plane, though.
