Yeah. Definitely emphasize the importance of figuring out (and writing down) during slotting and confirming during briefing which squad you're in, how it will be addressed on the radio, which channel to be on, and who your direct superiors are so you know what to listen for.
As a noob, I sometimes end up thinking I'm in "Bravo" because my unit description says "1-1-B 4" in the map screen when in fact I'm in "Alpha" because 1-1-A is command or whatever, and then getting in the wrong truck, being on the wrong radio channel, and generally causing chaos for others and embarrassment to myself.
As a note to mission designers - this could definitely be improved in many missions, often it's totally inconsistent between the slotting unit names, the com/sig card if there is one, and much of the time the commanders just end up doing alpha/bravo/charlie anyways.
