These two are correct, >>183202398>>183202457
but to further expand on that pic,
Top Row: Revolutionary War ship flag, NCR from Fallout, Gallian flag from Valkyria Chronicles, Nuko from SSR/Girls Last Tour
Second Row: American Flag, Griffion and Kruger negative and positive patches, GDI Eagle, Nod Scorpion both from Command and Conqor, and on the far right you can see a bit of IDW longcat from GFL.
Third Row: Baka tab from Cirno fanart, Squad 7 and Squad 422 from Valkyria Chronicles 1 & 3 respectively, Combine Overwatch logo from Half Life, Umbrella Corporation from Resident Evil.
Bottom Row: XCOM logo, polland ball cannot into space meme patch, Upotte high school patch, and Ghost in the Shell Stand Alone Complex
I like anime and game patches.
