Redsec improvement

Hi I would like to suggest some change regardless redsec 

First one will be on "tank accessibility" , tank are strong tool in redsec yes but are still extremely easy to obtain even with the recent changes.

-I recommend at first to remove the possibility to obtain the key simply by looting crate it doesnt make sense to have acces to a tank by just looting boxes specifically at the start of game. Players should work harder to have access to that powerfull tool 

-Secondly I will recommend to change how the key is obtained through missions my recommendation will be that players MOST complete and/or intercept(counter) 3 missions to have acces to tank key mission by doing that it will created fair balance on how to get a tank, like I mention tank are strong yes but players must work to gain access to it.

Classes:

-Recon drone should have it thermal remove the drone is already quite powerful in itself due to its ability to fly at very high altitudes so it allow player to mark player across the map ( As for the air strike thermal I pesonally feel its already balance since it visual is in "straigh line" so  if you wish to spot someone the other side of the mountain you need to climb it to scan across)

-Engineer rocket ability should no longer one shot players im not against that it do damage but it should NEVER one shot 

-Add plate box to assaulter instead of it ladder
