It seems the tinfoil cover on the rear of the IFV is just a temporary cover for the air intake/radiator that's on the left of the vehicle. The next gen MBT also have similar cover during transit.
Not sure why they're needed, considering none of the other vehicles have similar covers.
The Observer is right. And the more you look at it, the less traditional the vehicle´s layout is compared to other IFVs. The entire aft left hull section is occupied by the radiator (rather huge) and the "box" on the roof looks like is part of something that protrudes into the compartment, may indicate its indeed a VLS for ATGMs.It looks like an empty box and not like radiator. By the size of the hole VLS seems more reasonable.
This image is not all that clear but it looks like theres a bulkhead separating the dismount compartment/access corridor and the "VLS".

On one hand, the radiator being so big and being on the side hull creates a weakpoint. However there are no dismounts sitting besides it so the whole issue is somewhat mitigated. On the other hand, most other IFVs/AFVs with L layout powerpack that place radiators on the side hull they mount them on the frontal section, hence endangering the crew/dismounts to a greater degree.
The aft section layout hence looks something like this (not to scale):

Though we don´t know if there is a set on the access "corridor" (ie. right underneath of the roof hatch) it looks to me unlikely that this IFV can carry more than 7 dismounts, which would be the same as current in service IFV.
