Welcome to the sport!!!
All I can say is that it’s kind of a rabbit hole in some ways, and be prepared to have a new hobby!!
I have been shooting the RTC for a few years now and I sure can’t recall coming across a barricade before, not saying you couldn’t, but it’s a little different COF vs PRS. As previously stated, you’ll probably have a few prone stages, a few positional stages(utilizing natural terrain), and expect to see a mover. Tall bipods/shooting sticks are highly recommended to shoot from high kneeling/sitting, and Tripods can come in handy to have along.
But my biggest advice to you and your buddy is to really work on your communication between you. As a team match, that is absolutely critical to be able to communicate efficiently between each other. I have personally witnessed some amazing individual shooters really struggle with this team aspect. So really work on calling corrections for each other, reading the wind together, and making a plan together. Decide and practice who’s ranging the targets on the blind stages, who’s shooting first, and so on.
I’m a huge fan of the team aspect, it’s a ton of fun, a great community of people, and both of those matches you spoke of are absolutely amazing places to burn gun powder at.
Good luck, holler if you have any other questions, and hope to see you and your partner out there!!!
