First...I took a look at your profile...you've seen how much of LFCA? (I've never served in LFCA, only within LFAA and at CTC) I am guessing that your post above is based on what you've seen in your former PRes unit(s)? I am not sure I would want to paint that brush so widely on the Officers, WOs, Snr NCOs, Jnr NCOs and soldiers in Pet at 2 CMBG/units. Again, I've never served in LFCA but I have worked with and known lots from there. My first experience with folks from LFCA was in '92 on Basic Para at (then) CABC and I can't remember a single person on that course from Pet that fits the post of yours above, or the Res Cmbt Engrs from LFCA units that were on the course either. They were ALL fit, keen, able soldiers. And I've worked with many since then. Sure, some weren't the sharpest knife in the kitchen but...neither was I. Maybe your opinion on your capabilities and fitness will change when you hit Wainwright...
Be careful with the wide "LFCA" brush...just my $0.02.
