G1n032: Yes, you really stack up, and the usual deciding factor is what you're packing; for example, you don't send a SAW gunner in first. In training, with a normal infantry team, we usually stack up "ready, team, fire, assist" - meaning the team's rifleman, team leader, automatic rifleman, and assistant automatic rifleman. Variations take place in actual execution, usually with the squad sending the most experienced in first, followed by any SAW gunners armed with M249 Paras the squad might have. Everyone does it a bit differently; there's a little bit of art to the science.
