There are many features lacking in the game.
I turn to

Ai movement- cover utilization is ♥♥♥♥
-needs to focus on ai response to gunfire
-ai response to commands to follow along walls
-ai response to seeing ai they should call it out and start the assault if aggressive approach is on
-look to tarkov for better ai mechanics and look at how scavs respond to player movement, actions that can drastically make the game seem ultra realistic given the game is dependent upon ai patterns.
-ai to path find into buildings and utilize buildings via command or follow [player] command

Ability to build sandbags and use for cover Ai can get command Foxhole setup and they just can assemble either foxholes or sandbag walls to use as cover

have on/off option because divide in community on subject"
vehicles [correct issue so ai can use vehicles properly and bring them back in]
