I took it fairly face value, or at the least the first verse could be about a "lost" battalion in WWII. Surrounded and cut off, they're (the enemy) calling (artillery) on all downs (foxholes) you once made home.
Get poetic enough and the second verse could definitely sound like an pre-engagement artillery strike. Mixing it in with a metaphor of safety (a bank) and a collection (a bank) of guns (hydraullics).
Third verse could be the attack, coming from all sides, wanting the same things you hate (your death). Here they come, the people you don't care for (the enemy).

Just some thoughts.
