Gun spawns seem to have been all but removed from any non-military locations, and a lot of the smaller military areas have been removed as well (tents in cherno/berezino, fire stations don't appear to be military). I've found pistols in schools of all places, but have yet to find any ammo. Food/water spawns feel about right, not swimming in it, but never really starving if you explore houses. Clothing is kind of neat so far, but quickly just turns in to another type of backpack you have to hunt for (find cargo pants and a parka as soon as you can for more slots etc).
Once you do make it to an airfield though guns are plentiful, as well as larger backups. Ammo is still a no-show though and I've passed by half a dozen m4s now with no way to fire any of them.
