I have trained at both Aldershot and Gagetown and know people who completed their CAP/BMQL at Aldershot although I completed mine in Gagetown. The delivery of this course is under active review and based on the latest issue of the infantry journal it is now 11 weeks instead of 10 and will no longer be delivered in Mods. Whether that approach will prevail is uncertain given the critical shortage of trained officers in the reserves but that is the current information being communicated from the infantry school.
How do they compare in:
Difficulty Gagetown is harder
Quality of learning Depends on instructors, Gagetown is often but not always better
Facilities Gagetown
Resources Gagetown
Time off Aldershot typically will provide a more 9-5 schedule, although to some extent it is this way in garrison in Gagetown as well
Also I was wondering if we have weekends off while on these courses (one officer I talked to said it's 6 days a week) Previously if you were not in the field then weekends are off unless confined to barracks (expect that to happen especially at the start of course)
The few officers I've talked to strongly recommended Aldershot because it's an easier course and everyone parties on their off time. I'm not big on partying and Aldershot is quite a ways away from my home town so I'd probably not have much to do on time off but if I go to Gagetown then I could drive home on weekends. You are assuming that you get to choose; the army will likely make this choice for you...I would say that any combat arms officer should be hoping for Gagetown over Aldershot as it will enhance success on trades courses.
I'm hoping this course won't be like BMQ. I found that the the learning pace is incredibly slow, the course material is boring regulations instead of soldiering skills, the instructors are lacking knowledge about basic course material, the pt is pathetic, and the troops are unmotivated (not trying to sound like an a**hole). I can guarantee that you will be challenged on this course. It will be completely unlike BMQ in terms of expectations and I strongly encourage you to adjust your attitude because yes you do sound like a bit of an arrogant a**... PT will not be pathetic, you will have much to learn and much will be expected of you.
Training in Gagetown may provide you with better preparation for your trade training depending on what that is. Last summer they ran a platoon out of Gagetown that was exclusively infantry and I don't believe that prospective infantry officers were permitted to attend the course anywhere else.
BMQL/CAP is a good course and as long as the staff are good (and they typically are), and you commit yourself to the training, you will be well prepared for your future military career. With a slight attitude adjustment you will also end up having a lot of fun and make some great friendships. Best of luck.
