I'm not quite sure of what the following in red is saying.
Show your support for them, particularly during challenging times. Let them know you have their back.
Thank you.
It's another way of saying let them know you support them.

NOT A TEACHER
(1) At the present time, this is a very popular expression in the United States.
(2) Let's say that 10 police officers have surrounded a building in which a bad man
is hiding. Let's say that one of those officers has to enter the building to find him.
The officers might say something like: "We've got your back."
(That is, we will do everything possible to support and protect you. If necessary, for
example, we will rush into the building if we conclude that you need help.)
I get it.
Thank you all for the help.
[QUOTE=TheParser;826824]I think the origin is even more literal than merely that they will come to his aid. It literally means that he can move forward (advance) into a situation (like combat) without worrying that some danger will come from his rear. Fellow officers/soldier are watching behind him, so he can advance. They have his back.
Another version is that they "I've got your 6," with the 6 o'clock position the person's rear (they face 12 o'clock).
Dave, I was thinking about adding the "I've got your 6" to the thread, but didn't. I"m glad you did.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
