Honestly, trailers linked with C3 or better of course C3i for perimeter defense (hull down behind a berm) and AA duties make a lot of sense. A turret with a LB-5X, Snub PPC, LRMs for throwing out Thunders, and LAC/5 to pepper targets would be pretty useful. More with double blind so the masters are hidden in buildings or behind ring berms . . . maybe give them two hovercraft spotters for a whole company net of C3 . . . and of course, artillery on the masters for indirect support.
The berm/sandbagged idea was for hasty defense. Ideally, the trailers would be turreted, with the trailer buried, with only the turret exposed. The network would be hard wired to thwart ECM.
Shouldn't that go in the fan designs section rather than here?
It was an example, not a submission. My point is, in the IS, especially among mercenary units, thinking outside the box is a freedom that few other forces have. The trailer idea was to equip a low-budget insurgency that had plenty of conventional, civilian vehicles and little in the form of military-grade hardware, aggravated by a competent blockade.
The scenario was meant to be a campaign for a veteran wargamer, who commanded an all-vehicle regiment. He had all the 3050-era equipment a Davion unit could afford and faced an impoverished, popular uprising that employed Capellan military advisers and a mercenary mech company. They cobbled together a smattering of obsolete military vehicles but their backbone was infantry and technicals (weaponized civilian vehicles). Since the world was primarily agricultural, there was insufficient industrial base to make any front line vehicles and weaponry but they managed a variety of retro-tech solutions, including trailers and wagons as weapon platforms.
Face it, how good would mech scanners work on a formation of horse-drawn artillery or other mech-grade weapons?
