Yes.
Special missions, manual page 122 ff.
Very short description (since you seem to insist not to read the really helpful manual):
# support-defence: moves to support attacked units in adjascent regions, needs only
half the time to normal move order, manually ordered
# reserves: same as above but automatic once set
# anti-partisan duty: doubles the suppression value of the unit,
very helpful in regions where you need to supress partisans, best done by garrison-units
General rule of thumb for land combat:
You
win battles best and fastest by depleting the org of the enemy units and for this you use combined arms, mainly inf/art for mostly stationary units, infantry without brigades as your bread and butter unit, MOT and ARM(=tanks) for the spearheads and airforce to support battles according to Schwerpunkt-doctrine (thus Air Mission: ground support targetting morale is better than ground attack, both can be done by either TAC, longer range, or CAS, more damage).
You destroy enemy units by either:
- Blitzkrieg tactics (Wehrmacht): encircling them until they have no more region to retreat (which will delete them in the next defeat in a battle). Encircling is done by armored spearheads: Panzer plus MOT but usually you try to keep them out of combat so they can actually move to encircle... which means you will strife to do the actual fighting with your infantry
or
- Deep Operation tactics (Red Army) by overrolling them: you defeat an enemy unit, they retreat to a region but a unit of yours is there earlier which will delete the retreating enemy unit upon arrival (best for this are MOT - motorized units because they are the fastest)
- (Wehrmacht) and (Red Army) shall only hint to the early developers of those tactics, the tactics themselves can be used by any country/army.

What choice of units, especially land units, is heavily dictated by your choice of tactics and your bottlenecks. If you have lack of manpower you counter this by going for more expensive but more manpower efficient units like air units, MOT, ARM. If IC is your bottleneck, simple inf are best and most efficient. If oil and/or TC (transport capacity) is your bottleneck, use as few oil- and supply-hungry units as possible.
