Halving combat strengths

[Blackcloud6]

There is no restriction as to how many times a unit's firepower can be halved in the rules.

A disrupted 7-4 HMG unit in an assault hex would thus attack with 2 strength (7 x 1/2 x 1/2, total rounded up).

Thanks.  It must be game confusion.  Too many rules rolling around in the attic.
