Now that some ships require supplies it would make sense to have supply ships or maybe just add supply radius to the large landing craft. It would also make it easier to support ground units that require supplies when you manage to pull off a beach landing.
Also, does it still make sense that the large supply depot can build halftracks now that halftracks no longer deploy? Wouldn’t it make more sense if it built regular transport trucks? Or maybe there could be a dedicated supply truck that doesn’t carry troops or tow packs/leigs but deploys into stockpiles with large-ish radius.
