I imagine the man has not been in an IFV doing a stab run with a driver and gunner who only graduated DP1/RQIP 3-5 months prior, and a crew commander who just finished PLQ and ISCC (and he himself only has been in battalion for 4-6 years at this point) before.
The rifle section has already been an arms locker for the past 20-30 years as far as the doctrine and the experiences of the NCOs that have taught me view it: every private coming off of BIQ/DP1/RQIP (or whatever else we want to call it now) for the past two decades has been qualified on the following weapon systems: Pistol (HP or C22), C7 (to include the use of a LAD and NVG), C9 (to include the use of thermal and night sights), C6 LR (to include the use of thermal and night sights), M203, C13/C13A1, SRAAW-L, SRAAW-M, and C19 CDDW.
That's not including all the remaining STANO and communications equipment they have to qualify with on course, along with patrolling, offensive, defensive and enabling operations modules (to include doing all of which in urban areas). Followed by field firing, rappelling and CQC-B.
And despite all of the above, having worked with the British and Australian training establishments, we have the most watered down base line infanteer qualification syllabus in the Commonwealth (not a feat to relish in) and for some stupid reason, despite the recommendations of the RQIP QSTP writing board and the Infantry School: the reservist inf bn command teams want the course to be even shorter even with the massive training delta the reservist infanteer already has.
The issue isn't the civilian joining the infantry corps, they handle the course content just fine on average so adding another 2-3 weapon systems is hardly a monumental feat for them. The issue (as it always has been) is passing off the buck to battalion to finish off the initial training of the soldier; where the soldier should show up to battalion with the ensemble of skills required to be further refined and given advanced skills (actual advanced skills, not qualifications on fundamental equipment and weapons that should've been on DP1 in the first place).
100%, and thankfully there is a project or two focusing on LF mobility - just would be cool if there were more airlift to move the battalion and that future capability around.
