For blunderbusses and the flintlocks I think Nobunaga also used straw mats or haystacks as barriers in their formations (I guess these are also more abundant and easier to carry around than making sandbags at those times?).Well.. its actually pretty simple: sandbag is a legit shield againts bullet and it can even hold a 9mm from modern gun, I think? (never test it myself).
that boils down to thickness of the wood and weight, a 68 caliber brown bess musket will blow through up to 4in (101mm) of common pine at 50-75 yards using early European tactics, so the big monsters would have to be moving battlements, being that the mentioned firearms resemble early matchlock designs it may vary, but a simple plank shields wouldn't be effective, iron on the other had could be. Also anyone can fill and place sandbags quickly and even under fire. an old saying i used to hear was "Cover is Key" meaning those who have proper defensive positions(ie cover) fare better than those out in the open.why waste time putting sand in a bag just use wood that's slightly angled it worked for the japanese against musket fire
plus you can move it if you march forward
he did to mixed results, a blunderbuss is a glorified shotgun, so a haybale/stack my stop it, but a lot of early flintlocks would go clean through, what he was banking on was his troops speed and poor accuracy of the enemies smooth bore muskets to get close and do damage, if i remember right he did a lot of ambush and hit and run tactics with his "riflemen" instead of European style lines of fireFor blunderbusses and the flintlocks I think Nobunaga also used straw mats or haystacks as barriers in their formations (I guess these are also more abundant and easier to carry around than making sandbags at those times?).
For a guy who’s supposed to be a tactical genius he’s a fucking idiotThey had no one collecting the dropped guns after battle? That's a quick way to get your shit reverse engineered. Just like we are currently seeing.
