Spring RTS Engine

It's not that hard to build interiors. Before thinking about Spring, I was going to consider using GMStudio, which would make the task a bit harder. The hardest thing in Spring is its LUA scripting, but its 3D mapping system is a bit attractive, which would make more beautiful maps.

Hey, I'm a bit new to Spring, want to know if it's possible to make a Swat 2-like game, in which you only had a team of 4 to 6 members to complete missions, and each member had their own function in the team.

If yes, are there any learning sources(tutorials)?

Thanks.
