Some units test new equipment and tactics, so it really depends on the unit, and what it is doing. Every unit in the military has a specialized purpose. For example your not going to send a communications guy out on a combat patrol as the gunner, or combat arms guy to the radio room to encrypt the radios.
As for units, they wouldn't be using truck drivers to stage an air assault when the Cavalry RSTA units are trained to.
Hope that was simple enough to understand.
Basically, see if the unit can be identified and you will have your answer as to what they are doing.
For all we know they are a bunch of part time reservists or national guard doing a disaster recovery drill. If they are active duty, thank god, because they know wtf their doing. And the part timers should watch and learn.
