You should be able to use chem lights underwater as nothing in real life would stop you and throw them when it the surface. This was something that was removed during Alpha because people were throwing grenades and blowing themselves up underwater.

Place diver, try to use chem lights underwater.
Theoretically, nothing stops you in real life from throwing chem lights or other objects underwater. Seems they disabled this unrealistically for lazy people who always blew themselves up.
In RL not all glow stick sink, just as not all float, some are very slow to sink, some will only sink so far before they become neutrally buoyant, others will do conversely opposite if released at depth, one trait they ALL share is in water that has flow/currants they are useless unless tethered to something or water flow/currants will move them very easily, another trait is many (NOT ALL) that DO sink don’t lay on their side on the bottom, they take an end-up attitude due to any airspace and/or the displacement characteristics of the plastic housing and the position of the activator capsule within.
Likewise, if you compared the same make of glow stick, different colours would have different propensities to sink/float due to the different mixing ratios of the base chemicals in order to produce a specific colour.
Anyway the ones in the game sink relatively slowly mostly in a horizontal attitude and lay on the bottom in a horizontal manner lighting up quite a large surrounding area, BUT there are no flow/currants in the Arma 3 sea even with maximum waves and bad weather to move them around!
Why was throwing gernades and other objects disabled in the first place? It can happen underwater so why disable it? If you throw a gernade underwater, you live with the consequences not get the devs to disable it because your too lazy to remember not to do so yourself!
Dropping chem-lights, or possibly throwing grenades (through the air) while swimming/treading water on the surface might be useful (although potentially suicidal), but "throwing underwater" is physically impossible - there is far too much drag through the water to even move your arms fast enough, and then too much drag through the water for an object like a hand grenade or chem light to travel more than a meter.
Explosives are also far more dangerous for people in water than they are in air due waters incompressiblilty. You would be likely killed by any grenade explosion within throwing range. See links: http://science.howstuffworks.com/explosion-land-water1.htm
I'm not really sure why this was removed in the first place. Chemlights in particular should be usable underwater as they can be use for marking or path tracing purposes.
Imagine a night time mission with an SDV insertion, you could use chem lights to mark you way back to the SDV.
The underwater chem light is not a bad idea, it'd make for neat stealth missions underwater at night. However, throwing grenades underwater is totally pointless. Sure you can do it in real life, but in real life you can also pick your nose while doing the robot, but they're not about to implement that. However, throwing grenades while on the surface of the water would not be a bad idea, especially if it's a diver insertion. Overall this was down voted, seems too silly and impractical.
Actually wouldnt mind the ability to throw chemlights. They look really awesome at night underwater, i suggest people try it.
Grenades? Why not, you wouldnt be able to throw them far due to water density, so would be something to watch out. Why was this removed, i have no idea, seems silly, to take it out.
