It’d be foolish to make too many concrete judgments about how a new army will play in the pre-release period (especially as we all know that there’ll be inevitable, post-release patching once it’s out in the wider world), but it does appear to be a force intended for a certain flexibility when playing alone, and a more specialised role within a group of allies.
That’s a particular branching choice from one building, but a similar dichotomy runs throughout the British faction. As the names suggest, these respectively expand the firepower and durability of the faction by opening up new units (a tank on each branch) and unit abilities things like tanks with ‘war speed’ on the Hammer branch, and quicker engineer repairs under Anvil. The British Forces feel as though they can loosely be defined by the either-or ‘Hammer’ and ‘Anvil’ tactical options which can eventually be unlocked from the tank-constructing Company Command Post building. Take that, you bloody bastarding bumless ninnies!
