If we are going EM 2 then....No thanks. To complicated. Too expensive to make.
FN made a
Bullpup version of the FAL with a 24" barrel which given that its a FAL means its better than.
Have this and belt fed bren type weapon in the original
.270 Enfield and not the later
.280 and .280/30 as these were much more powerful rounds much closer to the .30 and .303 rounds they were trying to get away from.
The 270 was a 100 grain / 6.5 gram bullet - whose long range performance was not as good as say .30 or .303 but was superior out to 300 meters (a range band at and below which the mass majority of infantry combat takes place) and controllable on full auto
So I think the FN FAL Bullpup - possible a para version with a shorter 20" barrel and a Belt fed Bren - both in .270 would make for a very decent Section/squad level combination.
The Bren and FALL are staggeringly easy to field strip and very reliable and one would hope that a Belt fed Bren would be just as simple and reliable as the OTL WW2 one was
Please note that the Taden was an MMG and fired from a Tripod - I do not know if a 'GPMG' version existed or was intended to be developed - the Belt fed Brens came after the EM2 and Taden projects ended and ultimately the FN MAG was chosen and existing Bren guns modified to 7.62 Nato.
However all this came about as a result of WW2 combat experience (Both British and German.....and technically US as well but they chose to ignore it) and so we are back to pre war ammunition and arms.
