Free War Games

War games in the browser favour the quick over the deep. The thirty-hour grand strategy simulators don't fit in a tab; the half-hour tactical battles do. The picks below cover tank duels, top-down squad combat, base-building wargames, and a few first-person military shooters.

All HTML5, all free, all browser-based. Most rounds run between five and twenty minutes, which suits a single sitting. If you want a war game without the install commitment, this is the list.
