Gadget Ideas for Assault and Recon.

ASSAULT CLASS

LVG Grenade launcher. A bouncing grenade that may bounce off the wall and land nearby on the ground. I am not a big fan of the sticky grenade Launcher because players will abuse it in narrow maps. 

Smoke Grenade Launcher. Smoke Grenade Launcher dedicated to the Assault Class. Normally, smoke was used by that class to cover the player movements, obscure the enemy's position, and assault the contested position.

Rally Point with ammo and meds. Instead of having only a Redeploy Beacon, an additional med and ammo station/supply. No explosives to be collected on Rally Point as grenades, Claymores, C4, Rockets, AT mines, etc. Assault suffers from a lack of ammo, and instead, there could be something finally useful.

RECON CLASS

Smaller one-winged drone. A small drone that is fast and might be used in narrow spaces. Hardly detectable and practically inaudible. May spot enemies up to 100 metres. Standard camera, no thermal vision,

Explosive Drone. Slower drone than MAV for balancing purposes. Something like a drone in BR that has an explosive payload. Extremely useful against vehicles. Less effective against infantry for the proper balance. One single hit to the drone should destroy it immediately.

Standard Goggles. Non-reflective goggles with high magnification. Sniper could use this instead of risking being spotted.

PISTOL

Taser. Basically, electrocuting the enemy player at very close proximity. The cable should be deployed with a small delay and travel at a slower pace, so hitting someone would require some practice. Could burn a player for 3.5-4 seconds. A friendly player may save a teammate.
