In my conception of the SL role, you are a NCO. In most armies, NCO know their men, their men know their NCO, at least a little.
So, being known a little, at least, in your squad, as a PFC or other roles is of essence before going SL.
Except if you are known battalion-wise, being on Squad-Random and SL is a risky gamble.
________________________________________________
Authority =/= Power : Authority is given to you by the status/rank. The system gives it to you. But, Power is what you gained. Power, is what is available to you, at this very moment, to enforce your authority.
As a NCO, you have nearly no power for enforcing authority towards someone. So, you have to find other ways to have authority and be obeyed. Usually, as a SL, you find power through charisma, in your ability to get people focused on what you are saying. Also, reputation is also a great way to gain power in a squad, being robust, brave, nice, wise, is an unvaluable asset.
Marine mechanic Vs Player will
Even if the server is medium roleplay, you are not facing marines, with a long and hard training, but still players, behind their PC. They have their own expectations, with their desires, with their will to play with or without you.

Communications
Players do not tend to be mindless sheeps. You have to deserve their respect and their will to follow you. One of the most useful tools at your SL's disposal is : COMMS.
As a SL, you have to spend at least 40 to 60 % of your time having comms with your men/the command staff and if you can, other SLs/PO/RO. Why ?
SL to Squad ( :h )
If you are a PFC, you spot something, you tell it to your SL and he ignores you. What do you do ? Keep on telling useful intel ? Knowing that it would not be heard ? You'll simply shut your mouth, and just play on your own.
If you are a squaddie, asking for something, and if you are also being ignored, will you accept being ignored, especially when you have to ask for critical things ? (Supplies, help, fire support, and so on).
You can't say "Yes" to everyone, but at least, copy their comms. Show your squad that you are listening. Show you squad that at least, you acknowledged what they told you.
SL to Command ( :v )
As a SL, you have 3 possible people to speak with : SO, XO, CO. It goes nearly the same way as the squaddies. Talk to them, acknowledge, don't be affraid to report any difficulties or your insight from the situation. Sometimes, what you report was in a blind spot for Command.
For the RO/PO/Other SLs, you can talk to them via command directly. They are nice guys, and are really willing to help and to ensure marines victory. If the SO doesn't do the link, make the first step :
- Ask PO if they are available.
- Ask RO about their business, the order you have to make.
- Tell other SLs about what you are doing, if you are need their help somewhere or to flank, to hold while you are doing a flank.
Motivation/Morale/Loyalty
You can't be sad on the frontline. You can be RPing sad things while you are off the fight though. But on the frontline, you have to keep encouraging the bros.
When someone gives you a smart tip ? Thank him.
When someone fucking kills that big thing over there ? Tell the marine who fucking badass he/she is.
Keep talking to your support roles (Medics/Engies), they are not killing, but they are improving your surviving chance.
To sum up the feelings there can be felt on this basis :
"Trust, is something that you feel when you don't see a threat towards someone. Loyalty, is the will to take risks for that person without thinking about it."
When I see someone sacrificing himself to save me, I'm fucking sad behind my PC, but also fucking amazed by the courage it took for that person to take his balls and to save me, at the cost of ending his round. But they'll keep doing it, without second thoughts, if you worth being saved.

The beginning of the round : talking about Chain of Command
The little technical tip I can give, is to explain what the chain of command is a the very beginning of the round. If your spec wants/is able to lead, ask him first. Spec is your second in command, but, if he doesn't want to lead, do not force him. When being forced to lead, you usually obtain medicre leadership.
Corporals can take leadership, but usually, they have already busying roles to fulfill (exception for the smarty, but usually smarties are not leaders).
Explaining the chain of command is for you a reason to focus the boys on your comms for a minute. They'll see your nickname, they'll see your way to talk. They'll see that you expect the unexpected.
The beginning of the round, prior to deployment, is really important for you. Because you have no threats and you can freely talk to your boys and girls. You can joke with them and create a bond which will have his very use later in the round, or in every round after.

Conclusion
It is clearly not the perfect leadership-guide, as it is really personal and deeply linked with my way of living and thinking, but I hope some of you aspiring-SL can discover or understand a few specific things about leading people.
I deeply apologize for my grammar mistakes and so on, well.. I still have some improvments to make on my English !
