A very sensitive subject for a lot of people - lets avoid past hostorical events and deal with the future:
1) It is unlkely that Canada will require an entire battalion of jump-trained soldiers. Why? Because it is highly unlikely that we will ever conduct aggressive attacks that require an element of surprise by attacking into a rear area and then waiting for armoured link-up. Why? For several reasons; no particular enemy to conduct such tactics on, no armour, no operations that require that tactic, not enough troops to conduct such a tactic, and not enough aircraft for such troops to jump out of.
2) However, it is of the utmost importance that soldiers have a higher level of achievement to aspire to. The US has a multitude of such forces i.e. green berets, rangers, marine recon, seals, delta, etc. all in a set hierarchy of achievement. We need a similiar system in order to allow soldiers to demonstrate their motivation and self-determination, to distinguish themselves from others on the same level. In this regard, it is very important for us to have a 'next level' that soldiers can achieve through intense pyhsical effort and determination. Such soldiers are then allowed to demonstrate their unqiueness by wearing different clothing, berets, and recognition than the 'other' levels wear.
3) However, again, such soldiers, having proven themselves to be a superior level than those beneath them, by successfully meeting the demanded standard, although grappling for the title of 'elite', then must realize that they ARE NOT the top of the food chain. They are merely a selection phase that weeds out those with lesser physical standards and determination. It is from this INTERMEDIATE achievement of jump-qualification that many of the next level of elite forces are selected; SAR, CSAR, JTF, SSF, Strat Recce, to name a few. To reach this next higher level, soldiers must continue to demonstrate physical expertise but must also demonstrate mental capabilities which seperate them from those with merely physical expertise.
4) On a point sure to enrage airborne-proponents, a jump course is a qualification on par with other specialized skills that seperate soldiers from others who passed 'basic' training. This includes mountain warfare, air assault, diving, hand-to-hand combat, markmanship, specialized intelligence teams, and other groups with unqiue skills related to combat zones and tactics but not involving a parachute. All are equally unique, and all require a higher standard than the normal soldier. Some require more physical skill while others demand higher mental skill, but all require the demonstration of a higher level of skill, and none can do the job of the others to the same standard (despite many claiming that they can or do). Elite forces select from these groups in addition to the jump-trained solderis, a fact that many jump-trained soldiers tend to forget.
In Summary:
I do not believe that there is an operational requirement for an entire airborne unit, due to the lack of CF operations and tactics that would utilize such expertise. However, I do believe that it would be a travesty to eliminate the opportunity for soldiers to gain this skill, or the recognition that soldiers gain by achieving this skill. Soldiers need a level of achievement to attain, a mountain to climb, a means to show themselves better than their fellow soldier. It is also an excellent means of proving that a soldier has the drive and determination that is sought by elite units higher up in the chain. Further, if Canada were to ever actually go to actual war and need this skill it would be a travesty to have eliminated the tactial and operational capability by having no one who knew how to jump out of an airplane, or to train others to do same. Finally, until someone invents an anti-gravity belt, transporter, or some other means of moving soldiers from an air platform to the ground, this will remain a required skill area and thus must train our soldiers for its potential use; do not eliminate a strategic weapon for the projection of power unless you have something to replace it with!
Thus endeth the lesson...
