Closing thoughts

The MAC-10 is a fantastic weapon with stunning movement accuracy (a fantastic trait for a Terrorist SMG) and low cost. It is kept balanced by its low armour penetration.

The MP5-SD is a silenced SMG that occupies the same loadout slot as the MP7; it's unique selling point is its silencer as the former deals more damage. Unfortunately this often is not enough to justify its high purchase price. However, a cheap (compared to a rifle) weapon that is silenced and has a high rate of fire can have utility in certain scenarios.
