Not sure of anyone has posted this yet but the recent Doctor Who edition of Risk contains 75 perfectly 1/72 scale Daleks. The game contains three sizes of Dalek in five different colours. There are 15 of each colour perfect for 1/72 (the other scales are too small/too large).
The sculpts are good but all of them are missing the sink plunger and eye stalk ends (easily added with your preferred modelling medium).
There are two types of Dalek: 'Classic' which are very nice (Grey, Black and Light Brown/Gold) - and 'New Dalek Paradigm' which are not particularly good interpretations of the much-maligned recent Dalek redesign (Orange and Yellow). Even so, you end up with 45 serviceable 'Classic' pepper-pots.
The big bonus is that the set also includes a 1/72 scale, dark blue Tardis.
The downside is the price: £40 to you, sir.
Of course, pitched against your lovely 'A Call To Arms' 1970s British Infantry, you can act out a Dalek Invasion repelled by U.N.I.T. troops.
Any other suggestions for similar scale figures to fit into this genre?
