Product Notes
Soviet P-40 1S12 Long Track Search Radar

Listed at USD 70.21 in 1/72 scale, this resin kit gives you a long, distinctive radar vehicle for a diorama centered on Soviet air defense. The model is 3D printed in photosensitive resin, with a 0.05mm layer pattern and support marks that you will need to trim, polish, and assemble. That makes it a build for someone with resin kit experience. The elongated track and radar mounting are more involved than the half-tracks in this group. The trade-off is the higher listed price and the amount of finishing work.
German Raupenschlepper Ost/1 Track Car

At USD 29.99, this 1/72 track car gives you a German tracked vehicle: the Raupenschlepper Ost/1. It is a resin kit in new condition and needs the same cleanup as the other prints, including layer marks and support traces. If your scene leans German, this is the only German option among the four. The lower listed price compared with the radar kit gives you a German subject without paying USD 70.21. The practical catch is that you still need to trim supports and assemble the parts before painting.
US M15 Half-track Gun Carrier

This US half-track gun carrier is listed at USD 28.99 in resin, with an unpainted 1/72 build theme. The product name also references 1/48 and 1/87 scale options, but the 1/72 version fits this comparison's scale. Choose it if you want a US vehicle with a clear gun-carrier role rather than a plain transport. The silhouette gives your diorama a different military purpose. Like the others, it requires support removal and assembly before it is ready to paint. At USD 28.99, it sits close to the lowest listed price, so the decision can come down to which US vehicle you prefer.
US M9A1 Half Track Vehicle

The US M9A1 half track vehicle is the lowest listed price in this set at USD 25.99. It is a 1/72 resin kit with unassembled parts and supports still attached. That makes it a sensible first pick among these unpainted resin kits, especially if you have not worked with 3D-printed resin before. The realistic limitation is that support removal and assembly are still on you; experience helps here, as resin prints need cleanup before painting. Your upfront outlay is the smallest of the four, but the finishing labor is no lighter than the others.
Final Recommendation
If you want a distinctive centerpiece and will spend time cleaning up a detailed resin print, the Soviet P-40 1S12 long track search radar at USD 70.21 gives you a bold silhouette. If you want a German subject, go with the Raupenschlepper Ost/1 at USD 29.99. For a US half-track with a gun carrier role, the M15 Half-track Gun Carrier at USD 28.99 fits well, and the US M9A1 Half Track Vehicle at USD 25.99 is the smallest listed outlay for a US build. All four need support removal and assembly, so match your pick to the scene you want to photograph or display.
