When doing SEAF artillery, gather the shells first so you know what you have and then turn on the console. Load them in the order you want them typically mini nuke > high ex > ex > napalm > static field > smoke.
When calling in supply, try to do so where it’s naturally where everyone is going to group up like on an objective or if you’re the first guy in line on the way to the next objective so people don’t have to run back.
If you’re split into two groups, try to ping the other teams guy to call in the reinforce before you call in someone away from their support weapons.
Sentries are better on high ground if available.
If shit is hitting the fan, anyone’s support weapons are up for grabs just give them back after.
So what does the Pokémon that runs around screaming “goatsucker” do?
