OKay - lets get the terminology correct.
you simply cannot have a 'sub-machine gun'. It is either a machine gun or not.

4. Thompson - .45 ACP - nuff said;
5. Uzi - Israeli Military Industries - Israeli's know their stuff;
6. Skorpion - horrible little Czech

7. Valmet - Finnish. Another little
8. H & K MP7A1 - another little beauty - Heckler und Koch, of course;
9. H & K G36C - another classic assault rifle which doubles as an SMG/SMP;
10. MAC 10 / 11 the classic John Wayne film smg - .9mm Mac or .45 ACP with sound suppressor hand grip, still a 'lively' contender - but a brute to
11. H & K MP5K - K for carbine - a little toy gun that packs a very big punch!
12. Sten gun Mk VI - .9 milly suppressed for secret agent man;
13. 7.62 mm PpSh - classic Russian WWII bunker broom;
14. Bizon 2 - another 'Russkie' with an attitude;
15. Steyr TMP - nice little Austrian (originally) and now a German.
