The Trumpeter kits are much better; however, they are not the current version used w/Iron Dome.
Both Trumpeter and Italeri kits are the older M1120A2 version.
The US Iron Dome is mounted on the latest M1120A4 version, which there is no kit of. There are parts on Shapeways to convert the A2 into an A4. They are quite pricey though.
Loaded on a US M1120A4 LHS, current version of HEMTT LHS.
