The mobs opening fire ahead are obviously just stalling for time, with no intention of fighting desperately with them.
This approach is exactly the situation that the guard squad leader is most unwilling to see.
After all, there are also large numbers of civilians rioting on both sides, and returning the way they came is even less possible.
Once their squad stops firing and leaves the Central Management Committee office building, it is immediately taken over completely by the rebels.
Presumably all the staff who refused to take the risk and stayed inside have already been killed.
Returning the way they came now would be practically suicidal.
The most troublesome thing is, the mobs who captured the Central Management Committee office seem to want revenge and have no intention of letting them go, as they chase them from behind.
The squad leader has no choice but to order his men to throw a grenade over, to see if they can deal with the ones hiding behind cover.
