Okay, I've just had a little idea.
As terrors on a bomb planting map, and the group is skilled enough. You could take 3 men to a bombsite, make a lot of fuss and keep it that way, trying not to die. Then, the other 2 lads (one of which has the bomb) after the signal is called that pretty much the whole CT team is taking to the bomb site the other 3 are at run around, plant the bomb.
This leaving almost the whole CT team at the wrong bombsite, they only have the option to kill the 3 terrors at the other site, for fear that as they run off to the other site then the terrors will run out shooting them in the back. So, if they do, manage to kill the 3 terrors it's going to be really tough on them to run to the other site, take down the last 2 terrors, and defuse the bomb going off.
