There was some asshole on here, damned if I recall who, suggesting a short tube 155 for general support at battalion or bde combat team level over a decade ago.
I like long ranged tube artillery, but if you're all stuck on stupid WRT fighting the mythical Soviets in some Gotterdamerung, you might want to figure out how you're going to call for fire in an intense ECM/ECCM environment. You retrans stations are going to get pounded, and point to point with VHF isn't going to fly at 30+km ranges, especially with jamming. So now you're looking at HF(sucks) or satcomm, which also sucks for different reasons. Having your firesupport range roughly mirror your comms range is probably a thing to consider. S/F....Ken M
