Combined arms clarification

[Navymule]

Our house group plays 2nd Edition rules.  We have playing under the assumption that for combined arms to be in effect, the two units must originate from the same territory.  However, I was watching a G40 strategy video and the maker was using combined arms even though the units did not originate from the same territory.

An example would be on G1, Germany used the fighter from Holland and the tactical from West Germany.  Does the tactical benefit from combined arms in this case?

Obviously(?), a mech infantry must begin its movement in the same territory as a tank to benefit from blitzing, right?

Are we playing this correctly or not?  :?

Good day NavyMule.
You have been playing that wrong. For combat, it does not matter from  where the Tac originates. The bonus is added (like your Dutch/ German example).
As you have said, it only matters for  movement: a Mech must move both spaces with a Tank to Blitz.

@Navymule:

This is correct for pairing a MechInf with a Tank for blitzing, only.

@rulebook:

Blitz: A mechanized infantry unit must normally stop when it enters an enemy controlled territory. However, when paired
one-for-one with a tank, it can make a blitz movement (see “Tanks,” page 27) along with that tank. The movement of both
units must start and end in the same territories.

All the other combined arms benefits apply to the Combat phase only. See the blue box on page 18:

@rulebook:

…
Some unit types require one-to-one pairing with
another unit type and may be paired with more
than one other unit type. Each unit may be paired
with only one other unit at the same time, but may
be paired with different units at different times
during the same turn. For example, an individual
artillery unit may not be paired with both an
infantry and a mechanized infantry during the same
combat round in the Conduct Combat phase in
order to make both units attack at 2. However, the
same mechanized infantry unit may be paired with
a tank during the Combat Move phase in order
to blitz, and then be paired with an artillery in the
Conduct Combat phase in order to attack at 2.

Thank you!  That makes such a huge difference for the Axis in the early game.

Also you can combine different arms into one big one and it still counts as I have clarified this. Example; Mech Infantry, Artillery, Tank, and Tactical bomber can all be combined for there strengths as long as it still remains a 1:1 ratio. And there is only one defensive combined arms which is destroyer allowing aircraft to target submarines.

To be clear about this:

@rulebook:

Some unit types require one-to-one pairing with another unit type and may be paired with more than one other unit type.
Each unit may be paired with only one other unit at the same time, but may be paired with different units at different times
during the same turn.
For example, an individual artillery unit may not be paired with both an infantry and a mechanized infantry during the same
combat round in the Conduct Combat phase in order to make both units attack at 2. However, the same mechanized infantry unit may
be paired with a tank during the Combat Move phase in order to blitz, and then be paired with an artillery in the Conduct Combat phase
in order to attack at 2.

@Caesar:

And there is only one defensive combined arms which is destroyer allowing aircraft to target submarines.

No. The combination is always valid, regardless of attacking or defending.

I mean the destroyer + aircraft rule isn’t exclusive to attack as combined arms likes to make it seem.
