Active duty guys, rather be deployed with reservists or guardsmen?

MAJ Byron Oyler often soldiers are offered Reserve component or Active schools, I always said first available, so I mainly attended Active duty schools.

MAJ Byron Oyler - The POI for reserve course such as NCO development is the same as the active, the main difference is at least on the reserve side the school day is longer to get all the material in and allot of night studying

MAJ Byron Oyler - That is absolutely untrue with the (fairly) recently adoption on STEP program. There was a time, back in the middle 2000's, during the surge when there was slightly abbreviated course for NG/RC. However the MOS-specific material was maintained in favor of things like drill and ceremony and other garrison leadership skills. Additionally, the NG/RC course went 7 days/week and often 10-12 hours in order to condense the time; Active courses were longer, but included weekends without instruction, or minimal instruction

The Army adopted a one-Army training model and use the same POI, often with mixed component classes. The main difference is the use of phases. Part time Soldiers usually have the option of breaking up the course load in20 3 or 3 week segments.

MAJ Byron Oyler - When I branch transferred when I moved to Kentucky, my Engineer Officer Advanced Course was two weeks, a correspondence phase and then a final two weeks to complete the course. I worked with both Guard and Active Engineer units afterwards, I never felt handicapped and just as a general observation would be that my Engineer Company would have ran rings around most of the active duty ones I have been associated. Most of that comes down to the fact that most of my guys did something related in civilian world, so my mechanics, operators, and demo guys had years more experience than some E-5 with four years in service.
Can't say the same about Infantry units, but it's simply that the National Guard training schedule doesn't have time to do large operations. My observation of Guard Infantry units is that they are generally decent at the Squad, Platoon and even Company level, but lack experience above that level.
The Air Force has done a much better job of integrating their Guard and Reserve assets.

Many Army Reserve Units in the Pacific Territories are also Combat Arms units. While the major reorganisation in the 1990's steered Combat Arms to the NG and Support Operations to the AR, the Pacific region was one that did not fall under the National Guard Bureau. My Active Duty time saw me in Air Defense Artillery, Maintenance, and Combat Engineers due to a demand MOS. while in ADA I was part of a Recon Team (RSOP), and as part of the training for that squad tactics were heavily trained. So in actually you may get a mixed bag of skillsets. Cheers.
