MALH-1 "Bottlenose" Hovercraft:
An ambitious small craft design intended to be fully amphibious, able to traverse over land and water with little difficulty on either. Capable of carrying a single squad into combat, whilst also able to engage light enemy units by itself with it's pintle-mounted .50 cal MG taken from the Yellowjacket. Mounting enough armour on the vehicle's upper half (Leaving the skirt unarmoured) to stop a .30 cal round and able to reach speeds in excess of 100km/h makes the craft difficult to deal with in it's preferred terrain.
Big, big, BIG -1. I think it is simply an awful way to spend a design action.
I dislike using aircraft weapon here, it is
purpose-designed for aircraft use, not general purpose heavy machine-gun. Hovercraft is unneeded +1 to cost tech that has little further use. Amphibious = bad at both roles. Not that good for fighting on land against real armor, incapable to travel long distances overs sea.
Pigeon Helicopter (outdated proposal)
A light, single rotor helicopter capable to carry pilot and 3-5 passengers or ~300 to 400kg of cargo. Part of its hull is made from wood at furniture factories to save ore cost. It is meant to be available in every infantry unit to cover liaison, recon, supply, medical evacuation and small scale landings behind enemy lines
[Vehicle, general, (if we can fit 3 passengers in very small, than very small, else 5 passengers and small), 1 ore, 2 oil, new tech expected: helicopters] ]
General vehicles are rather easy to produce and we will have them in many units few turns later
We can also revise a helicopter carrier from our transports, making a good landing option
