already use infrared (IR) and image enhancement scopes. We already have radar. How long before we
combine IR, radar, and visual light into images that are displayed on a combat infantryman's helmet visor?
The Air Force is already well on the way with its "Heads-Up Display" for fire control and navigation. We
adapted the HUD to the battlefield. If it's stifling, we can air-condition it. If our man wants a zoom
display, he can bloody well ask for it because his helmet computer will understand his spoken
commands. TAKE NOTE.
Among our biggest problems in Vietnam were the mazes of tunnels dug by the enemy. With luck, skill,
and deep-penetration bombs we cleared out some of those tunnels at great expense. Surely there must
be some way to develop a more subtle weapon that will find the tunnels and then go inside after live
targets. What, then; a robot?
Someone put previous researches together. After the work of Von Frisch with bees, scientists learned
how to "talk" to them by using a dummy bee. Evidently, a worker bee's "language" is literally built in to its
nervous system. In other labs, gene-splicing and restructured DNA show promise of modifying a bee's
nervous system. Insects already have the best chemical detectors in the world, for mating and
food-gathering. And bees have made hives in caves for a long, long time. Well?
The panel proposed an insect like a killer bee, bred for lethal sting and aggressiveness, and programmed
to seek certain chemicals common to the enemy, but not to our own troops. It might avoid the smell of
U.S. fatigues, while zeroing in on someone who smells of enemy rations. The bee would have a life span
of a couple of weeks, perhaps less (workers have short life spans as it is). Drop a few packages of those
sterile workers into a region honeycombed with enemy tunnels, and wait for your little live weapons to
acquire targets in the tunnels. If you have pheromone sensors to track the bees from a distance, you can
even locate the tunnel entrances—a great advantage in itself.
This "tailored hornet" concept seems less and less weird, the more we study it. We're not really making
the insects do anything that they don'talready do. We're just nudging them to do it exclusively against the
enemy.
A firefight can overwhelm the footsoldier with too much sound, light, odor, and touch. But if we encase
him in full body armor (TAKE NOTE), he will need some way to use information he gets through his
various sensors. For some years now, experimenters have been improving gadgetry that translates images
into patterns across an area, like finger-taps. Sightless people wearing this equipment can walk down a
street as if sighted, feeling painless taps in special patterns across their backs to warn of cars, curbs, and
other people. It should be possible to improve this equipment so that a soldier could wear it as part of his
battle dress. Will the information it adds be worth the trouble? It's still too early to tell.
Energy Transmission and Storage concepts ranged all the way from tiny rotary engines to beamed
microwave power. Early in the next century, men may have to fight on the surface of the moon. They will
need electrical power to run some of their systems. If our man is in deep shadow, he can't use solar
power. Could he actually use an oxygen-breathing Wankel rotary engine to power a tiny generator on an
airless planet? Sure he could; engine-driven torpedoes have carried their own oxygen supplies for many
years, and Lord knows there's less back-pressure in a vacuum!
Other energy storage candidates include batteries, ultracapacitors, and even very small particle-bed
nuclear power generators. The main problem is to devise a safe power of very high energy density and
reasonable cost. Whatever you use, you don't want an enemy bullet to turn it into a bomb. A particle-bed
reactor won't need refueling for a long time—but if it fails catastrophically, you won't care. A capacitor
delivers a wallop of power, but must then be recharged. Small flywheels can store tremendous amounts
of energy inside three-axis gimbaled mounts—but when that flywheel reaches the limit of its tensile
