Not sure if this is a known issue (I did read back many pages and also check the alive mod.com forums prior to this post), but I am not seeing parachutes attached to vehicles that have been requested and dropped via the Player Combat Logistics system.

Ammo etc arrives as it should (all be it without the sound effect of a passing plane as in versions past) with parachute and Red smoke grenade attached

No Parachute - they just Appear where the Airdrop Marker was. No explosions, no falling from the sky....just magic, lol
