I always liked LEAP. Col. Lenard doesn't ring a bell, but me and names don't get along. I use that part of my brain for other things. I was a contractor advising the SDIO office for a while and did several budgets for them (for just one budget round), then I moved on. Wasted tremendous amounts of money.
Plenty of uncertainty about the direction of programs and how they would pan out. Particle beams were promising, until they realized that it would be impossible to aim them accurately through the Earth's magnetic field. Space-based lasers were interesting, until they realized it would mean storing huge quantities of liquid hydrogen and liquid fluorine in space for the lifetime of the system. Railguns were interesting, until they uncovered all the problems with rail erosion and the fact that the high-Mach projectile would start decelerating from the muzzle immediately at about 10 gs. But, as the Russians say, you can't make an omelette without breaking eggs!
One thing I pushed was solid state lasers to eliminate the decoys. That would make the overall problem easier.
I had a more fun concept. Nukes with massive lead cloaks. Detonation would create temporary high-density gas clouds that would produce aerodynamic filtering of the low-mass decoys from the heavy RVs. I figure what could a few more nuclear detonations hurt...in space...when you are already in the middle of a nuclear war?
