I was there today (21 Sep) for this mainly Land Warfare event. Block E Apache ZM704 was parked near the Concept Zone. Initially with most of the nose coverings on, which were removed when the Sun came out. I missed some helicopter flying in and out while I was indoors looking at the exhibits early on

.
Plenty of Boxer (8 wheeled) variants this time but perhaps unsurprisingly, not a single Ajax (tracked).
