Just... get in the damn Pelican.

Just lost 20 something samples because the guy holding them decided to plink at distant enemies with his AMR instead of getting on the ship. He just stood there shooting until the timer ran out.

You don't need to fuck around, you don't need to throw airstrikes or orbitals, and you don't need to shoot random stuff. Just get in, and finish the mission. Shouldn't take more than 4 seconds for everyone to get aboard when the Pelican lands.
