Is it possible to add a UKF style icon to them as part of the upgrade, so you know when the buff is active? (for when only some of the squad are in crator cover, etc, as they are 7 man).
Also, it might be worth speeding up the molotov throw, especially now that the US have them and actually throw them at a decent speed, rather than in slow motion.
It currently shows a sword on the shield icon for those with the 7man upgrade.
