I have suggested this point many times before and most players done the same. Years go by, but so far there is no response from the developers on this fairly logical and quickly “fix”/update.
The current Gold order system is unfortunately outdated with so many new weapons and military equipment in the game. All Gold orders should become one universal order. Because there are full of players who specialize only in certain aspects of the game, and some orders are completely unusable (like me, where I don’t focus on tank game-play at all) and if we were awarded with universal gold orders, we could choose ourselves where we would like to use it. Whether for a soldier, or a weapon, or a tank/aircraft.
Also, there should be an opportunity to be awarded Gold orders much more often.
