So the statement "Platoons equipped with PRR accomplished missions quicker and with less casualties" was arrived at through the results measured during training.
As I have stated before there is of course some value in the PPR system but the problem is that it blocks off one ear to natural sounds and therefore effectively halves the aural situational awareness of soldiers. I agree with Fuchs that with the use of an earpiece which does not block natural sounds yet feeds in the PRR traffic is a relatively simple fix given todays available technology.
We tried the radio earpiece for stick commanders back in 1976 (in Rhodesia) mainly to allow the commander to keep both hands on his weapon at all times. The push to talk pressel switch was built into the FN hand grip to be thumb operated.
There were two problems, one the pressel switch was not robust enough and two, nobody found closing off one ear acceptable.
You see Wilf you can catch soldiers who have seen little or no combat with the "smart" idea of closing off one ear but you don't catch the old and bold.
Now because of the PRR the soldiers can't locate the "thump" and now need locating radar (at GBP10,000 a pop) to do what two ears can do pretty easily.
We have discussed this before... people who have not seen significant combat should not be leading the design and implementation of equipment to be used by combat troops. This is just another good argument why not.
