Good day, these are various books posted by the Singapore Defence Science Organisation on their past projects. The scale of these books are rather in-depth for basically coffee-table books, and include A-4SU, the various 155mm howitzers, AMX-13 and more. I hope that by posting this I help someone with their research, or on something they wished to find out.
If I posted wrongly, apologies, I really am not familiar with forums.
I've also inserted the files directly in case they're taken down.
