Space 200 worth it?

Hello, I keep getting requests from an O-3 in my unit to go to Space 200. He’s an 8yr capt. I’ve never been, but feel like I’ve been in space so long there’s nothing in that class for me except a nice break from ops (pulling 50-60hr weeks).

if I let him go that means I have to cut someone else’s TDY since it’s unit funded. For those who have been, can the material really not be self taught? Is it more an “expand your network” thing?

Update 12/15: thanks everyone for the inputs. I could’ve worded it better, alas, I’m a burnt out dad running on fumes. Will try to help this guy get his funds, looks like there’s some other avenues others pointed out I wasn’t aware of. Thank you!
