Beirut 1982 diorama

I've never tried a diorama before, but the base will be a road or track, with a culvert running under it (Woodland Scenics Concrete Culvert). One side of the culvert will be destroyed with an IED strike. Above it I'll place a burnt out Merkava I (I will need to develop some weathering skills). Responding will be a Magach (M60) with a dozer blade, together with two Zeldas with troops setting up a cordon, and two M151 Djapas pulling security.
