Of course, this ice is really made for Thunderbolt Armaments: Peace Through Power. But even out of that identity, it is still a fairly good ice. It compares to Unsmiling Tsarevna : 3 subs, 4, 2 strength. Those are good numbers. Most runner would not like to let any of the subs fire... ever. Making this ice a 3 cost of passing this ice, usually (few runner can play Orca). This let you grind the runner's credit pool.
Again, just like with Lycian Multi-Munition, there are many good ices in the HB card pool. This ice would be a good choice for identity such as Thunderbolt Armaments: Peace Through Power and Asa Group: Security Through Vigilance, who can profit the most from it. Protecting an asset like Working Prototype behing this ice is enough deterence most of the time. Otherwise, a corp will probably get more mileage from Drafter.
Of note, this ice pairs well with ZATO City Grid, by allowing the corp to rig shoot the most important card from the runner. Especially in Ob Superheavy Logistics: Extract. Export. Excel.. 4 to trash something important (a breaker, a console or an important connection), while getting a 3 other card (like Sandstone), it is a good bargain, even at 3 influences.
Art is nice and goes well with the name of the card. The quote seems nice and appropriate. Good job.
