Targeting engineers

[Dog Soldier]

The solution is just as simple as has already been said. Protect engineers by keeping them out of LOS. This why there is a rule to allow engineers to ferry infantry across a river. The infantry push enemy units out of LOS of the crossing site and let the engineers work unmolested.

Naturally, as the attacker one uses copious artillery to protect the infantry on the far shore until the bridge is built.

Night time is a great opportunity to lift enemy mines and clear lanes for the dawn attack.

One just has to think a bit about period tactics before committing highly trained and expensive units to the battle. Losses among one's engineers, being specialists, garner higher per man VP. This reinforces the correct tactic to cause losses on the opposing side's engineers when they are exposed.
