"Indeed. Redlegs Rule! Annie was at Sill the last time I was there just under 30 years ago in the outdoor museum artillery park. I think the 155mm nuke has only been tested underground to make sure it will go 'boom'. I spent a couple of years at Sill playing with those toys. BTW, did you know about the time in the '50s when a 240mm round was fired out of safe into the intersection of Sheridan and Gore?"
I was watching Modern Marvels the other night and they just built the first ever GPS guided artillery gun/shells. No where to run, no where to hide.
Even with GPS guidance, you'll only get within a few meters of the target. Laser designation (with Copperhead guided projectile) works well if the antomospheric conditions are possible.
What's less appreciated is that in the old days, a really good 8" (203mm) howitzer crew, with a good tube, registered, good data on the met, powder, etc., a good FDC and first order survey, could reliably put a round in a target the size of a largish door. (Specifically, an inert round put through the door to the Blockhouse on Signal Mountain for all you Redlegs who've been to the Commanche County Cannon College) - I first heard about that from a guy who was there during WWII, but I saw demonstration batteries put 8" rounds on specific car/truck body wrecks out on the range in the mid-1970s.
