Would be great if we could store weapon and items in vehicles.

If Ubi would introduced items weight and cargo limit to player that would be even more fun. It's kind of wired to play immersive mode and having 350 kg of automatically collected items in 3 day pack and still be able to do sprint run.

Imagine for immersive mode if you can take like a rifle, pistol, mags, some ammo, grenades, one mine and one or two C4 on you, plus some food, bivyy, medkit and that's it, but in your vehicle you may have additional 5-6 mines, a box of grenades, few boxes of ammo, more C4, MANPAD with 4 rockets, ect. Having vehicles would be even more fun this way.

So far in the game we have only 3 day pack at maximum. An addition of Bergen like rucksack would be great and then...

Weight limits linked to movement speed would be perfect. Like 10kg able to sprint for some time, 20kg sprint for much shorter and just slow jog for longer. 30kg-40kg slow jog for short and mostly walk. 40kg+ only walk.

This leads us to having in game: 1 day pack (10kg), 3 day pack (20kg), Bergen 60L (30-40kg) and Bergen 120L (40kg+). I know math I've done isn't perfect, but gets us somewhere closer to realism than it is now.

And to make it more fun - option to drop cargo - so rucksack goes down and we're left with vest and weapon only to break contact fast

This is about immersive mode mostly.
