PDWs...and other small arms.

[LRRPF52]

The problem is that often the support troops are doing patrols. Not staying in an office. Yes if you are a foppet then you may not need a rifle. But few support troops are staying within the wire. More and more of our combat injuries and deaths are among the support troops, not infantry.

The Tavor is a modular system. It can be configured as a rifle, a carbine or as small as a SMP. Multiple calibers and barrel lengths.

Most of the weapons mentioned are too big. The Thompson is. But then even the P90 is about the same size as the Tavor.

Remember that the PDW has to not only fit on a belt but also be effective out to 300m.

If you are task-organized to conduct active patrols outside the wire, the PDW is not something you want to be carrying unless you're an RTO, Combat Medic, etc.
