Moral boost meaning what? Something like being less suppressed?
Overall thoughts
As for the actual point of the thread, I spent all day yesterday squad leading and enjoyed it very mcuh (and finished first in points every round and it wasnt through kills).
Like one person so far mentioned, you can indeed give orders to the 3 different fireteams you have in your command or you can just give it to all of them. Assault, rifle and machine gunner are these fireteams.
It seems that when Commander dish outs orders to squads, they will only fall down to squad leaders. So from there on it's the Squad Leaders responsibility to repeat the same order down to their squad or the members will have no idea such order was ever made.
Personally the way I decided to overcome many issues mentioned here was just the spawning on squad leader. I can't effectively control whether every squad member will do what I want, but I ensure that I give out orders (either according to commander if it's a good one or usually "improvise" cos the commander does nothing) and follow them myself.
For example, I played Aparments as soviets fairly much yesterday and saw people rush in and cap fe. Propaganda House and then just leave it empty and go for the park. So cos others seemed to enjoy rushig, I told my squad to defend Prop. House, and sticked around there myself. Alot of people spawned on me. Some of them probably left the house, but they kept spawning on me so it somehow worked.
So it's alot down to the SL to do what they order themselves, this way the lazy majority will most likely attempt to spawn on SL to avoid the long run all the way from spawn and they will automatically be in the right place.
It was very important to stay alive myself to keep the squad action going so in Fallen Fighters I admit of having cowardly been proning behind a safe wall near Central Park alot, but if I died, it would mean that we most likely would've lost the spot. I did however also get some 40 kills within two rounds there while staying alive very well. Topped the scoreboard in overall points every time, the people hugging the building windows didn't come even close with their kill points.
Future suggestions?
But yes, I too am looking forward to some things:
1) Perhaps the squad members should not have an option to accept/decline, but at the very least, show me how many accepted/declined/didnt reply. If nothing else, I can kick (if not possible, make it) said people out of my squad and hope that more competent people take the spot. Commanders can see which squads accepted/declined the order, so why can't SL see what the members said?
2) Indeed clearer indications of where my members are as well as for the members to easily find me on the battlefield
3) Maybe better instructions on SL responsibilities when you are picking the class (sorta goes for commander too, nobody knows what they are doing) and maybe clearly saying that they need to forward the Commander's orders onwards to their squadmembers
4) Squad VoiP, would love to have any functioning VoiP as it won't transmit my voice for whatever reason -_-
5) Perhaps some kind of "officer chat" within a faction? Perhaps as a VoiP too, but even a text channel that the Commander and SLs could only read.
6) Incentives (read: POINTS!

) for SLs to follow Commander's orders, as well as incentives for members to follow squad leaders orders. Perhaps Commander should get something if they assigned Squad 1 to capture Obj.A and it was indeed captured by Squad 1. Overall speaking being a commander seems pretty unrewarding. You are stuck watching a map most of the time, barely get any kills except artilleries and you wont really get any teampoints either, even if your master plans would've won the mission.
Final words
I suppose this thread is also partially tied to it's time. I've seen a lot of progress on most players in these few days. I wouldn't expect anyone to be able to be really useful to the squad on their first day of playing. My experience as a Squad Leader yesterday was fantastic, however.
