The last few patches I've on multiple ocassions noticed friendly vehicles and squads disappearing. They just vanish into thin air, possibly respawning closer to the fight? I don't mind if the game does this to balance things out a little but it shouldn't happen where a human player is at that moment. Breaks the immersion...
Similarly, I've also noticed enemies spawning on the battlefield itself, often even inside friendly territory. It's very demotivating to have finally pushed an enemy back into their own zone when suddenly 5 more pop up out of thin air right in front of you.
Does this happen online or offline?
Online could be explained with having an occasional weak sync situation, together with the issues that concern offline too.
Offline it can happen for 1) you're carrying a sniper rifle which allows you to see to the inactive region of the world, so when troops move in to active region from the inactive region, you see them created as physical soldiers, 2) areas with water are problematic together with point 1, the soldiers in the inactive region don't care whether they are in water or not, but when they are created after reaching the active region, they favor being created onto a nearby platform (bridge or dock) if the block has deep water in it.
3) It is also possible to see in the inactive region in a place where a downhill approaches north from your standpoint or if you're on a kind of peak (building or hill). This together with point 1 and point 2 obviously increase the chances of having to see people created into characters.
Would any of these fit your experience?
Note that the soldiers never spawn in groups in thin air (except paratroopers which the AI doesn't use), the sudden appearances of groups of soldiers is always related to the points I presented. The game doesn't use spawn hacks to make it harder or balanced, eww

This stuff has been there since forever, with point 2 making an entrance sometime after map5 was introduced, as it uses some heavily watered areas that are also meant for soldiers to move in.
