We're playing a game, and a player is claiming that you cannot move within 1" of an ally without activating assault.

Is he correct?

as for allied units there are no real rules, since 40K rules only cover one on one games, if you are playing two on two or more you have to make up the rules yourself.

However, the restriction on moving within one inch only applies to Enemy models, not friendly models as noted on Page 11, under "Models in the way".

You simply cannot move within 1" of an enemy with the exception of the assault phase, which is done when you declare a charge.

You may move as close to your own allied units as you want, and you may never assault allied units.

Can you move your own squads within 1" of each other?
If yes, then yes you can.
If no, then no, allies may not be within 1"
