My problem with Squad rules is while they protect a PC they totally de-power the entire group. Instead of almost a dozen individuals or even a couple of groups of minions and a PC taking actions you get a single action with a boost die. So really these rules only work if the enemy is doing the same thing. Then you get many more short turns of battle instead of a few long turns of battle. It wouldn't work at all when you are fighting something like a Star Destroyer with a Squadron of X-Wings. since it would still be a single piddly attack versus the Star Destroyers Capital ship actions.
Unless you roll a Triumph on your combat check. If you do you can spend it to have the squad make an attack as an applicable minion group. Pretty nasty if you have an HBR and the minion squad is equipped with one as well.
