it work better, if u are behind cover and fighting and use command, "round on me", however, if u are not behind cover, and use command , " on fire" they generally are easily down, and getting mission fail , esp against wolves and in the mission. what i think , even dropping command of on firing, they should work more cautious or smart, dont' keep forward without caring their HP, esp in open area, they are just moving forward , forward and forward. i think the command is asking them to open fire ,but not too aggressive without help to player. they can work more suppressive from opening fire, but there was no need to aggressively moving forward.
