Well here is the main list.
VTOL
British Aerospace Harrier II (8 hardpoints, 2 are reserved for air to air missiles) but can deal with Hawker Siddeley Harrier (5 hardpoints) Equippable equipment is the same for both. Only the amount of equipment depends.
Helicopters
For transportation of cargo, equipment CH-47 Chinook.
Choose this over Sea knight because bigger load capacity (12,700 kg of cargo and 33–55 troops), bigger speed and bigger range of operation.
For combat purpose attack helicopter, Russian Mil Mi-28
Good equipment, can be used in all-weather, day-night conditions. Russian made, so can handle Siberia.
For Infantry transport and infantry support. Russian Mil Mi-24
Reason: Better support for infantry and variable equipment.
Reason why it took long.
In real life, were remodeling the kitchen. Mother wants a new fridge and oven.
