Also using Subterranean and Robotnic Drone tech we can make Spider and Widow mines from StarCraft.
Ok since we have tunneling tech we could tunnel under specific areas then blow it up and make the enemies fall in tunnel areas. so far very far down.
Well underground hunter killer could be fun.
Future research designs:
-Spider mine:
Using our knowledge on both Ai/remote control, and burrowing/subterranean technologies, we present the concept of a highly advanced semi mobile mine/limpet.
These drones will use their advanced AI to bypass any enemy countermeasures and plant themselves in areas where they will do the most damage. Then they will plant themselves into the surroundings and wait for valid targets. Upon detection of valid targets in a condition that has been preauthorized, the drone will decide how to engage the targets. They can decide to act as a traditional mine, pop out and charge an enemy position, or latch onto targets and detonate(tanks). The advanced AI allows for this weapon to be highly discriminate, optimize it's effects on the enemy, and enhances it's stealth by positioning it self to decrease the likely hood of detection.
-Mole:
The mole is a modified subterranean chassis that has a highly advanced AI allowing it to conduct deep operations into enemy territory. This chassis is highly difficult to detect and can act as a decoy(run a gap generator to trick the enemy into believing our forces are present), deployment platform for other crafts(Spider mines, Voles), or act as a deep sensor tracking enemy actions. The inbuilt cloaking, gap generator, and shielding combined with it's digging speed allows this craft to be highly survivable. This craft is armed with a single light weapon(to prevent infantry from rapidly disabling the craft from diving back into the ground) to enable it to survive very light attacks.
-Vole:
This is a stealthy subterranean munition that can be used to either deep attack enemy fortifications or to kill a surface target from the ground. This craft will use the subsurface as it's travel medium, stealthily searching or moving to it's target. When it finds it's target, the craft will make an approach underneath and then detonate. The effect of the detonation looks very similar to a deployed spider mine which also helps to demoralize the enemy(It is hard to trust that you are in a secure area when there was what looked like a widow mine that blew up your convoy/foxhole).
Hope these look good.
EDIT: removed cloaking for the expendable munitions
