>>5661462If we're going that far, why bother with traditional ammunition or even caseless? Go full gyrojet, bolter, Metal Storm, or chemrail.
With their technology, you could probably go XM25/XM29 with actual self-guiding ammunition that doesn't need manual programming.
Though, half of the above is probably overkill in all but the most dire of situations, and may be best kept in reserve.
